Linear Technology LT1963
the LT1963 regulators have very low output noise which makes them ideal for sensitive RF supply applications. The LT1963 regulators are stable with output capacitors as low as 10µF. The devices are available in fixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V and as an adjustable device with a 1.21V reference voltage.| Part No. | LT1963 |

The devices are capable of supplying 1.5A of output current with a dropout voltage of 340mV. Operating quiescent current is 1mA, dropping to < 1µA in shutdown. Quiescent current is well controlled; it does not rise in dropout as it does with many other regulators.
