DESCRIPTION
The STV8163 is a monolithic triple positive voltage
regulator designed to provide fixed precision output
voltages of 3.3 V, 5 V and an adjustable voltage for
currents up to 0.6 A.
The adjustable value of the third output can be fixed
from 2.5 V to 16 V.
An internal reset circuit generates a reset pulse
when the voltage of Output 1 drops below the
regulated voltage value.
Outputs 2 and 3 can be disabled by a digital input.
Short-circuit and thermal protections are included in
all versions.

voltage which can be due to an overload of pin OUT1
or by a lack of Input Voltage (VIN1).
