DESCRIPTION
The TDA8139 is a monolithic dual positive voltage
regulator designed to provide precision output volt-
ages of 5.1V and adjustable at currents up to
750mA.
An internal reset circuit generates a reset pulse
when the output 1 decrease below the regulated
voltage value.
Output 2 can be disabled by TTL input.
Short circuit and thermal protections are included.
