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 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

in all the versions.

This is advance information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
