LT1965EDD#PBF Datasheet PDF - Linear Technology

The LT1965EDD#PBF is a low noise micropower low dropout Linear Regulator that supply 1.1A of output current with a 310mV typical dropout voltage. Operating quiescent current is 500µA for the adjustable version, reducing to <1µA in shutdown. Quiescent current is well controlled, it does not rise in dropout as with many other regulators. The LT1965 regulator has very low output noise which makes them ideal for sensitive RF and DSP supply applications. Output voltage ranges from 1.20 to 19.5V. The LT1965 regulator is stable with output capacitors as low as 10µF. Internal protection circuitry includes reverse-battery protection, current limiting with fold back, thermal limiting and reverse-current protection. The LT1965 series are available in fixed output voltages of 1.5, 1.8, 2.5, 3.3V and as an adjustable device with a 1.20V reference voltage.
