LDO Voltage Regulator

500 mA

These linear low drop voltage regulators provide up to 500 mA over

a user−adjustable output range of 1.25 V to 5.0 V, or at a fixed output

voltage of 1.5 V, 3.3 V or 5.0 V, with typical output voltage accuracy

better than 3%. An internal PNP pass transistor permits low dropout

voltage and operation at full load current at the minimum input

voltage. NCV versions are qualified for demanding automotive

applications that require extended temperature operation and site and

change control. NCP5500 and NCV5500 versions include an

Enable/Shutdown function and are available in a DPAK 5 and SOIC 8

packages. NCP5501 and NCV5501 versions are available in DPAK 3

for applications that do not require logical on/off control.

This regulator family is ideal for applications that require a broad

input voltage range, and low dropout performance up to 500 mA load

using low cost ceramic capacitors. Integral protection features include

short circuit current and thermal shutdown.
