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.
