Description
The TL1963A-xx devices are low-dropout (LDO) regulators 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 inshutdown. Quiescent current is well controlled; it does
not rise in dropout as with many other regulators. In addition to fast transient response, the TL1963A-xx
regulators have very low output noise, which makesthem ideal for sensitive RF supply applications.
Output voltage range is from 1.21 V to 20 V. The TL1963A-xx regulators are stable with output capacitance 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 1.5V, 1.8 V, 2.5V, 3.3 V,
and as an adjustable device with a 1.21-V reference voltage.
