Product Overview

The LT1964ES5-SD#TRMPBF is a 200mA low noise micropower negative Low Dropout Regulator 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 30µVRMS over a 10Hz to 100kHz bandwidth. It 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.
  • Low noise (30µVRMS, 10Hz to 100kHz)
  • Low quiescent current (30µA)
  • Low dropout voltage
  • -5V Fixed output voltage
  • Adjustable output from -1.22 to -20V
  • Positive or negative shutdown logic
  • 3µA Quiescent current in shutdown
  • Stable with 1µF output capacitor
  • Stable with aluminium, tantalum or ceramic capacitors
  • Thermal limiting
