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.
