Product Summary

The LP5951MFX-3.3 is a low-dropout CMOS voltage regulator. It is designed to meet the requirements of portable, battery-powered systems providing a regulated output voltage and low quiescent current. When switched to shutdown mode via a logic signal at the Enable pin, the power consumption is reduced to virtually zero. The LP5951MFX-3.3 also features internal protection against shortcircuit currents and over-temperature conditions.

Parametrics

LP5951MFX-3.3 absolute maximum ratings: (1)Continuous power dissipation: internally limited; (2)junction temperature: 150℃; (3)human body model: 2kV; (4)machine model: 200; (5)junction temperature range: -40 to 125℃; (6)ambient temperature range: 0 to VIN+0.3V.

Features

LP5951MFX-3.3 features: (1)Excellent line transient response: ±2mV typ; (2)Excellent PSRR: -60dB at 1kHz typ; (3)Low quiescent current of 29μA typ; (4)8 to 5.5V input voltage range; (5)Small SC70-5 and SOT23-5 packages; (6)Fast turn-on time of 30μs typ.; (7)Typ. < 1nA quiescent current in shutdown; (8)uaranteed 150mA output current; (9)Output voltage range: 1.3V to 3.7V; (10)Logic controlled enable 0.4V/0.9V; (11)Good load transient response of 50mVpp typ.; (12)Thermal-overload and short-circuit protection; (13)-40°C to +125°C junction temperature range.
