TL1963AQKTTRQ1

The TL1963A-Q1 device is a low-dropout (LDO)
regulator optimized for fast transient response. The
device can supply 1.5 A of output current with a
dropout voltage of 340 mV. Operating quiescent
current is 1 mA, dropping to less than 1 µA in
shutdown. Quiescent current is well controlled; it does
not rise in dropout as it does with many other
regulators. In addition to fast transient response, the
TL1963A-Q1 regulators have very low output noise,
which makes them ideal for sensitive RF supply
applications.
Output voltage range is from 1.21 V to 20 V. The
TL1963A-Q1 regulators are stable with output
capacitors as low as 10 µF. Small ceramic capacitors
can be used without the necessary addition of ESR,
as is common with other regulators. Internal
protection circuitry includes reverse-battery
protection, current limiting, thermal limiting, and
reverse-current protection. The devices are available
in fixed output voltages of 1.5 V, 1.8 V, 2.5 V, and
3.3 V, and as an adjustable device with a 1.21-V
reference voltage. The TL1963A-Q1 regulators are
available in the 5-pin TO-263 (KTT) package.
