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.
