Product Overview

The LT1521CMS8#PBF is a low-dropout Regulator with micro-power quiescent current and shutdown. This device is capable of supplying 300mA of output current with a dropout voltage of 0.5V. Designed for use in battery-powered systems, the low quiescent current, 12µA operating and 6µA in shutdown, make it an ideal choice. The quiescent current is well controlled and it does not rise in dropout as it does with many other low-dropout PNP regulators. Other features of the LT1521 include the ability to operate with very small output capacitors. It is stable with only 1.5µF on the output while older device requires between 10 and 100µF for stability. Small ceramic capacitors can be used, enhancing manufacturability. Also, the input may be connected to voltages lower than the output voltage, including negative voltages, without reverse current flow from output to input. This makes the LT1521 series ideal for backup power situations where the output is held high and the input is low or reversed.
  • No protection diodes needed
  • Controlled quiescent current in dropout
  • Reverse battery protection
  • No reverse current
  • Thermal limiting
