NCP4632: Linear Voltage Regulator, LDO, Low Voltage, 3.0 A, with Reverse Current Protection

The NCP4632 is a CMOS Low Dropout, Linear voltage regulator with high output current capability (up to 3 A). This device can provide output voltages as low as 0.8 V while maintaining a low dropout voltage of 510 mV typ. at full load. The NCP4632 is designed to draw only 350 uA of supply current and less than 1 uA in standby mode to minimize current consumption for battery operated applications. The device has a high accuracy output voltage of ±1% along with soft start and reverse current protection circuits to protect the device and the application. The NCP4632 is available in a Pb Free DPAK5 package in both fixed and adjustable output voltage options. The output voltage for the fixed options can be modified in 0.1 V steps from 0.8 V to 4.2 V Please contact your sales office for any additional fixed voltage outputs to those already listed.
