L1183B - 300mA CMOS LDO

Datasheet Summary

Description

The UTC L1183B is a positive, linear regulator.

One of the feature is the very low ground current typically as low as 30μA, and the dropout voltage is extremely low.

For stable operation, the output capacitance value should be 2.2μF or more.

Features

  • Very Low Dropout Voltage.
  • Guaranteed Output Current: 300mA.
  • Quiescent Current: 30μA (TYP. ).
  • Typical Accuracy Within 2%.
  • Over-Temperature Shutdown.
  • Current Limiting.
  • Short Circuit Current Fold-Back.
  • Power Good Detector (6 pin version only).
  • Power-Saving Shutdown Mode.
  • Adjustable Output Voltages.
  • Low Temperature Coeffici.
