DESCRIPTION

The TDA8133 and the TDA8133D are monolithic

dual positive voltage regulators designed to provide

fixed precision output voltages of 5.1 V and 8.0 V

for currents up to 750 mA.

An internal reset circuit generates a reset pulse

when the voltage of Output 1 drops below the

regulated voltage value.

Output 2 can be disabled via the TTL input.

Short-circuit and thermal protections are included in

all versions.
