DESCRIPTION
The LT®1964 is a micropower low noise, low dropout negative regulator. The device is capable of supplying 200mA of output current with a dropout voltage of 340mV. Low quiescent current (30µA operating and 3µA shut down) makes the LT1964 an excellent choice for battery powered applications. Quiescent current is well controlled in dropout.
