DESCRIPTION
The TDA8138 is a monolithic dual positive voltage
regulator designed to provide fixed precision output
voltages of 5.1V and 12V at currents up to 1A.
An internal reset circuit generates a reset pulse
when the output 1 decrease below the regulated
voltage value (for TDA8138 and TDA8138B).
Output 2 can be disabled by TTL input (for
TDA8138 and TDA8138A).
Short circuit and thermal protections are included
in all the versions.
