Product overview
Overview
The LP2950 and LP2951 are micropower 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.
Features
• Pb−Free Packages are Available
• Low Quiescent Bias Current of 75 μA
• Low Input−to−Output Voltage Differential of 50 mV at 100 A 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 F Output Capacitor for Stability
• Internal Current and
Thermal Limiting
• NCV Prefix for Automotive and Other Applications Requiring Site and Control ChangesLP2951 Additional
Features
• Error Output Signals an Out of Regulation Condition
• Output Programmable from 1.25 V to 29 V
• Logic Level Shutdown Input
