Description
The STV8130A# and STV8130AD are monolithic
dual positive voltage regulators designed to
provide a fixed precision output voltage of 3.3 V
and an adjustable voltage between 2.8 and 16 V
for currents up to 750 mA.
An internal reset circuit generates a reset pulse
when the voltage of output 1 drops below the
regulated voltage value.
Output 2 can be disabled via the TTL input.
Short-circuit and thermal protections are
included.

1. This reset signal is activated by a decrease of V
OUT1
voltage which can be due to an overload of pin OUT1 or by a lack of
Input Voltage (V
IN1
).
2. The output short-circuit currents are tested one channel at time. During a short-circuit, a large consumption of power
occurs, but the thermal protection circuit prevents any excessive temperatures. A safe permanent short-circuit protection is
only guaranteed for input voltages up to 16 V.
