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.
