MARKING

The NCP4632 is a CMOS 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 mA of

supply current and less than 1 mA 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 DPAK−5 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.
