TDA8133 (5.1V+8V regulator with Disable and Reset)

(1) General Description

The TDA8133 is a monolithic dual positive voltage regulator designed to provide fixed precision output voltages of

5.1V and 8V at currents up to 0.75A.

An internal reset cuicuit 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 themal protections are included in all the versions.
