型号/规格： LT1964ES5-5
The LT®1964 is a micropower low noise, low dropout negative regulator. The device is capable of supplying 200mAof output current with a dropout voltage of 340mV. Lowquiescent current (30μA operating and 3μA shutdown)makes the LT1964 an excellent choice for battery-powered applications. Quiescent current is well controlled indropout.Other features of the LT1964 include low output noise.With the addition of an external 0.01μF bypass capacitor,output noise is reduced to 30μVRMS over a 10Hz to 100kHzbandwidth. The LT1964 is capable of operating with smallcapacitors and is stable with output capacitors as lowas 1μF. Small ceramic capacitors can be used withoutthe necessary addition of ESR as is common with otherregulators. Internal protection circuitry includes reverseoutput protection, current limiting, and thermal limiting.The device is available with a fi xed output voltage of –5Vand as an adjustable device with a –1.22V reference voltage. The LT1964 regulators are available in a low profi le(1mm) ThinSOT and the low profi le (0.75mm) 8-pin(3mm × 3mm) DFN packages.
