Micropower Voltage Regulators

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.

LP2950 and LP2951 Features:
• 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

LP2951 Additional Features:
• Error Output Signals an Out of Regulation Condition
• Output Programmable from 1.25 V to 29 V
• Logic Level Shutdown Input
