UCV676/A
LINEAR INTEGRATED CIRCUIT
400mA LOW-DROP VOLTAGE
REGULATOR
DESCRIPTION
The UTC UCV676/A is a low dropout voltage regulator with a
400mA output current used in harsh automotive environments. It
can be used in wide input voltage and operating temperature
ranges.
It has a high peak input voltage tolerance and reverse input
voltage protection. Built-in heat protection circuit, current limiting
circuit and inhibit control circuit. The UTC UCV676/A family is
available in TO-263-5 and TO-252-4 surface mount packages.
The output is stable over a wide output capacitance and ESR
range.
