Features & Applications
The LP2951CD-3.3R2G is a part of LP2951 series linear regulators. It has a storage temperature ranging from -55°C to +150°C and its available in SOIC-8 package.

The LP2951 is a micropower low dropout (LDO) linear voltage regulator that are specifically designed to maintain proper regulation with an extremely low input-to-output voltage differential. These devices feature a very low quiescent bias current of 75 µA and are capable of supplying output currents in excess of 100 mA. Internal current and thermal limiting protection is provided.


  • Low Quiescent Bias Current of 75 µA
  • Low Input−to−Output Voltage Differential of 50 mV at 100 µA and 380 mV at 100 mA
  • 5.0 V, 3.3 V or 3.0 V ±0.5% Allows Use as a Regulator or Reference
  • Extremely Tight Line and Load Regulation
  • Requires Only a 1.0 µF Output Capacitor for Stability
  • Internal Current and Thermal Limiting
  • Pb−Free Packages are Available
  • NCV Prefix for Automotive and Other Applications Requiring Site and Control Changes
  • Additional Features:
    • Error Output Signals an Out of Regulation Condition
    • Output Programmable from 1.25 V to 29 V
    • Logic Level Shutdown Input
