LP2950CDT-3.3RKG Datasheet

100 mA, Low Power Low Dropout Voltage Regulator


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 A 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 A
• 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
   Unique Site and Control Change Requirements; AEC−Q100
   Qualified and PPAP Capable
• These Devices are Pb−Free and RoHS Compliant

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