Product Overview

The LP2951ACDR2G is a 100mA, low power, low dropout (LDO) linear voltage regulator in 8 pin SOIC package. This micropower voltage regulator is specifically designed to maintain proper regulation with an extremely low input to output voltage differential. It features a very low quiescent bias current of 75µA. The LP2951 has three additional features. The first is active-low error output that can be used to signal external circuitry of an out of regulation condition or as a microprocessor power-on reset. The second feature allows output voltage to be preset to 5V or programmed from 1.25V to 29V. It consists of pinned out resistor divider along with direct access to error amplifier feedback input. The third feature is shutdown input that allows logic level signal to turn off or turn on regulator output. Due to low input to output voltage differential & bias current specifications, it is ideally suited for battery powered applications where an extension of useful battery life is desira
  • Internal current and thermal limiting protection
  • Maximum input voltage of 30VDC and 0.5% output voltage tolerance
  • Dropout voltage of 30mV at IO = 100µA and 350mV at IO = 100mA
  • Extremely tight line and load regulation
  • Requires only 1µF output capacitor for stability
  • Internal current and thermal limiting
  • Operating ambient temperature range from -40°C to 125°C
  • Line regulation of 0.04% (Vin=VO(nom) 1V to 30V) and load regulation of 0.05% (IO=100µA to 100mA)
  • Output noise voltage of 126µVrms (10Hz to 100KH, CL = 1µF)
  • Supply bias current of 93µA at IO = 100µA and 4mA at IO = 100mA
