Texas Instruments TL1963A Low-Dropout Regulator

Texas Instruments TL1963A is a low drop-out (LDO) regulator optimized for a fast transient response. The TI TL1963A can supply 1.5A of output current with a dropout voltage of 340mV. The operating quiescent current of this Texas Instruments LDO regulator is 1mA, dropping to less than 1µA in shutdown. The quiescent current does not rise in dropout as it does with many other regulators.
