DESCRIPTION

The TDA8137 is a monolithic dual positive voltage

regulator designed to provide fixed precision output

voltages of 5.1V at currents up to 1A.

An internal reset circuit generates a reset pulse

when the output 1 decreases below the regulated

voltage value.

Output 2 can be disabled by TTL input.

Short circuit and thermal protections are included.
