3 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 in

shutdown. 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 makes

them ideal for sensitive RF supply applications.
