NCP153 LDO Regulator - Dual, Low I

LDO Regulator - Dual, Low I _Q

130 mA

The NCP153 is 130 mA, Dual Output Linear Voltage Regulator that provides a very stable and accurate voltage with very low noise and high Power Supply Rejection Ratio (PSRR) suitable for RF applications. In order to optimize performance for battery operated portable applications, the NCP153 employs the Adaptive Ground Current Feature for low ground current consumption during light−load conditions. Device also incorporates foldback current protection to reduce short circuit current and protect powered devices.

Pin

Name Description

1 OUT1 Regulated output voltage of the first channel. A small 0.22 mF ceramic capacitor is needed from this pin to ground to assure stability.

2 OUT2 Regulated output voltage of the second channel. A small 0.22 mF ceramic capacitor is needed from this pin to ground to assure stability.

3 GND Power supply ground. Soldered to the copper plane allows for effective heat dissipation.

4 EN2 DrivingEN2 over 0.9 V turns−on OUT2. Driving EN below 0.4 V turns−off the OUT2 and activates the active discharge.

5 IN Input pin common for both channels. It is recommended to connect 0.22 mF ceramic capacitor close to the device pin.

6 EN1 DrivingEN1 over 0.9 V turns−on OUT1. Driving EN below 0.4 V turns−off the OUT1 and activates the active discharge.

− EP Exposed pad must be tied to ground. Soldered to the copper plane allows for effective thermal dissipation.

APPLICATIONS INFORMATION

The NCP153 is a dual output high performance 130 mA Low Dropout Linear Regulator. This device delivers very high PSRR (75 dB at 1 kHz) and excellent dynamic performance as load/line transients. In connection with low quiescent current this device is very suitable for various battery powered applications such as tablets, cellular phones, wireless and many others. Each output is fully protected in case of output overload, output short circuit condition and overheating, assuring a very robust design.

The NCP153 device is housed in XDFN−6 1.2 mm x 1.2 mm package which is useful for space constrains application.

Input Capacitor Selection (C_IN)

It is recommended to connect at least a 0.22 m F Ceramic X5R or X7R capacitor as close as possible to the IN pin of the device. This capacitor will provide a low impedance path for unwanted AC signals or noise modulated onto constant input voltage. There is no requirement for the min. or max.

ESR of the input capacitor but it is recommended to use ceramic capacitors for their low ESR and ESL. A good input capacitor will limit the influence of input trace inductance and source resistance during sudden load current changes.

Larger input capacitor may be necessary if fast and large load transients are encountered in the application.

Output Decoupling (C_OUT)

The NCP153 requires an output capacitor for each output connected as close as possible to the output pin of the regulator. The recommended capacitor value is 0.22 m F and X7R or X5R dielectric due to its low capacitance variations over the specified temperature range. The NCP153 is designed to remain stable with minimum effective capacitance of 0.15 m F to account for changes with temperature, DC bias and package size. Especially for small package size capacitors such as 0201 the effective capacitance drops rapidly with the applied DC bias.

There is no requirement for the minimum value of Equivalent Series Resistance (ESR) for the C

but the maximum value of ESR should be less than 2 W . Larger output capacitors and lower ESR could improve the load transient response or high frequency PSRR. It is not recommended to use tantalum capacitors on the output due to their large ESR. The equivalent series resistance of tantalum capacitors is also strongly dependent on the temperature, increasing at low temperature.

Enable Operation

The NCP153 uses the dedicated EN pin for each output channel. This feature allows driving outputs separately.

If the EN pin voltage is <0.4 V the device is guaranteed to be disabled. The pass transistor is turned−off so that there is virtually no current flow between the IN and OUT. The active discharge transistor is active so that the output voltage

disable state the device consumes as low as typ. 10 nA from the V

.

If the EN pin voltage >0.9 V the device is guaranteed to be enabled. The NCP153 regulates the output voltage and the active discharge transistor is turned−off.

The both EN pin has internal pull−down current source with typ. value of 300 nA which assures that the device is turned−off when the EN pin is not connected. In the case where the EN function isn’t required the EN should be tied directly to IN.

Foldback Short Circuit Protection

The internal foldback limits short circuit current to typical 55 mA and protects powered device against overheating.

Maximum output current is internaly limited to 165 mA (typ). The current limit and short circuit protection will work properly over whole temperature range and also input voltage range. There is no limitation for the short circuit duration. Thess protections are independent for each channel. Short circuit on the one channel do not influence second channel which will work according to specification.

Thermal Shutdown

When the die temperature exceeds the Thermal Shutdown threshold (T

− 160°C typical), Thermal Shutdown event is detected and the affected channel is turn−off. Second channel still working. The channel which is overheated will remain in this state until the die temperature decreases below the Thermal Shutdown Reset threshold (T

− 140°C typical). Once the device temperature falls below the 140 ° C the appropriate channel is enabled again. The thermal shutdown feature provides the protection from a catastrophic device failure due to accidental overheating.

This protection is not intended to be used as a substitute for proper heat sinking. The long duration of the short circuit condition to some output channel could cause turn−off other output when heat sinking is not enough and temperature of the other output reach T

temperature.

Power Dissipation

As power dissipated in the NCP153 increases, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration on the PCB, the board material, and the ambient temperature affect the rate of junction temperature rise for the part.

The maximum power dissipation the NCP153 can handle is given by:

Reverse Current

The PMOS pass transistor has an inherent body diode which will be forward biased in the case that V

> V

. Due to this fact in cases, where the extended reverse current condition can be anticipated the device may require additional external protection.

Power Supply Rejection Ratio

The NCP153 features very good Power Supply Rejection ratio. If desired the PSRR at higher frequencies in the range 100 kHz − 10 MHz can be tuned by the selection of C

capacitor and proper PCB layout.

Turn−On Time

The turn−on time is defined as the time period from EN assertion to the point in which V

will reach 98% of its

nominal value. This time is dependent on various application conditions such as V

, C

, T

.

To obtain good transient performance and good regulation characteristics place input and output capacitors close to the device pins and make the PCB traces wide. In order to minimize the solution size, use 0402 capacitors. Larger copper area connected to the pins will also improve the device thermal resistance. The actual power dissipation can be calculated from the equation above (Equation 2). Expose pad should be tied the shortest path to the GND pin.
