TO-252-9S (VA009-A)

HSOP-8A (FH008-A)

Output current : 500 mA (S-19318) ｜ 250 mA (S-19317)

This IC is a high-withstand voltage and low dropout positive voltage regulator with a reset function and has a built-in ON / OFF circuit, developed using high-withstand voltage CMOS process technology.
This IC operates at the maximum operation voltage of 36 V and a low current consumption of 3.0 μA typ. A built-in overcurrent protection circuit to limit overcurrent of the output transistor and a built-in thermal shutdown circuit to limit heat are included. Regarding a release signal output in the reset function, this IC enables delay time adjustment by an external capacitor.
