TDA8139, TDA8139/D
Double (5.1 V and adjustable) voltage regulator with
reset and disable functions
Features
■ Input voltage range: 7 V to 18 V
■ Output currents up to 750 mA
■ Fixed Precision output 1 voltage: 5.1 V ±2%
■ Adjustable output 2 voltage: 2.8 to 16 V
■ Output 1 with reset function
■ Output 2 with disable function by TTL input
■ Short-circuit protection at both outputs
■ Thermal protection
■ Low dropout voltage
Description
The TDA8139 and the TDA8139/D are monolithic
dual positive voltage regulators designed to
provide a fixed precision output voltage of 5.1 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 OUTPUT1 drops below the
regulated voltage value.
OUTPUT2 can be disabled via the TTL input.
Short-circuit and thermal protections are included
in all versions.
