Features & Applications
The LP2950 are micropower low dropout (LDO) linear voltage regulators 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.

Due to the low input-to-output voltage differential and bias current specifications, these devices are ideally suited for battery powered computer, consumer, and industrial equipment where an extension ofuseful battery life is desirable. The LP2950 is available in the three pin case 29 and DPAK packages. The 'A' suffix devices feature an initial output voltage tolerance +/- 0.5%.


  • 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 µA 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


  • Automotive
