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.
