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 m V. Operating quiescent current is 1 m A, 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.
