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.
