LT1764ET#PBF

LINEAR TECHNOLOGY  LT1764ET#PBF  电压稳压器, LDO, 可调, 2.7V至20V输入, 340mV压差, 1.21V至20V/3A输出, TO-220-5

The is a low noise/dropout Regulator optimized for fast transient response. The device is capable of supplying 3A of output current with a dropout voltage of 340mV. Operating quiescent current is 1mA, dropping to <1µA in shutdown. Quiescent current is well controlled and it does not rise in dropout as it does with many other regulators. In addition to fast transient response, the LT1764 has very low output voltage noise which makes the device ideal for sensitive RF supply applications. Output voltage range is from 1.21 to 20V. The LT1764 regulator is stable with output capacitors as low as 10µF. The internal protection circuitry includes reverse battery protection, current limiting, thermal limiting and reverse current protection. The device is available in fixed output voltages of 1.5/1.8/2.5/3.3V and as an adjustable device with a 1.21V reference voltage.
