Description

General part information

LT1964 Series

The LT1964 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 shutdown) makes the LT1964 an excellent choice for battery-powered applications. Quiescent current is well controlled in dropout.Other features of the LT1964 include low output noise. With the addition of an external 0.01µF bypass capacitor, output noise is reduced to 30µVRMSover 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. 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. The LT1964 regulators are available in a low proﬁle (1mm) ThinSOT and the low proﬁle (0.75mm) 8-pin (3mm × 3mm) DFN packages.ApplicationsBattery-Powered InstrumentsLow Noise Regulator for Noise-Sensitive InstrumentationNegative Complement to LT1761 Family of Positive LDOs
