DESCRIPTION
The STV8130A# and STV8130D# 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.
