DESCRIPTION
The TDA8133 is a monolithic dual positive v oltage
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.
