DESCRIPTION

The STV8130A and STV8130B are monolithic

dual positive voltage regulators, designed to pro-

vide precision output voltages of 3.3V and adjust-

able, at currents up to 750mA for STV8130A and

200mA for STV8130B. The ability to deliver cur-

rents is the same for the two ICs, but the higher

thermal resistor of PDIP8 does not allow to over-

pass 200mA for the STV8130B.

An internal reset circuit generates a reset pulse if

Output 1 drops below the regulated voltage value.

Output 2 can be disabled by TTL input. Short cir-

cuit and thermal protections are included.
