Product Summary

The LP2951CD-3.3G is a micropower voltage regulator that specifically designed to maintain proper regulation with an extremely low input-to-output voltage differential. The LP2951CD-3.3G features a very low quiescent bias current of 75 mA and are capable of supplying output currents in excess of 100 mA. Internal current and thermal limiting protection is provided. The LP2951 has three additional features. The first is the Error Output that can be used to signal external circuitry of an out of regulation condition, or as a microprocessor power–on reset.

Parametrics

LP2951CD-3.3G absolute maximum ratings: (1)Feedback Input Voltage, Vfb: -1.5 to +30Vdc; (2)Shutdown Input Voltage, Vsd: -0.3 to +30Vdc; (3)Error Comparator Output Voltage, Verr: -0.3 to +30Vdc; (4)Operating Junction Temperature, TJ: -40 to +125℃; (5)Storage Temperature Range, Tstg: -65 to +150℃.

Features

LP2951CD-3.3G features: (1)Low Quiescent Bias Current of 75 mA; (2)Low Input-to-Output Voltage Differential of 50 mV at 100 mA and; (3)380 mV at 100 mA; (4)5.0 V, 3.3 V or 3.0 V ±0.5% Allows Use as a Regulator or Reference; (5)Extremely Tight Line and Load Regulation; (6)Requires Only a 1.0 mF Output Capacitor for Stability; (7)Internal Current and Thermal Limiting.
