Product Overview

The LT1964IDD#PBF is a micro-power low noise/dropout Negative Regulator capable of supplying 200mA of output current with a dropout voltage of 340mV. Low quiescent current makes the LT1964 an excellent choice for battery-powered applications. Quiescent current is well controlled in dropout. With the addition of an external 0.01μF bypass capacitor, output noise is reduced to 30μVRMS over a 10Hz to 100kHz bandwidth. The LT1964 is capable of operating with small capacitors and is stable with output capacitors as low as 1μF. Small ceramic capacitors can be used without the necessary addition of ESR as is common with other regulators. The internal protection circuitry includes reverse output protection, current limiting and thermal limiting. The device is available with a fixed output voltage of -5V and as an adjustable device with a -1.22V reference voltage.
