) ^{■ Short-circuit protection at both outputs}
t(s ^{■ Thermal protection}
c _{■ Low dropout voltage}
rodu ^Description
P _{The TDA8133 and the TDA8133D are monolithic}
te ^{dual positive voltage regulators designed to}
le ^{provide fixed precision output voltages of 5.1 V}
o ^{and 8.0 V for currents up to 750 mA.}
bs ^{An internal reset circuit generates a reset pulse}
when the voltage of output 1 drops below the
- ^{O regulated voltage value.}
) _{Output 2 can be disabled via the TTL input.}
t(s _{Short-circuit and thermal protections are included}
uc ^{in all versions.}
