LP2992IM5-3.3/NOPB

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LP2992IM5-3.3/NOPB is a fixed-output, low-noise, ultra-low-dropout linear regulator from Texas Instruments. It provides a stable 3.3V output with up to 250mA load current capability. The device operates within an input voltage range of 2.5V to 16V and maintains high accuracy across varying conditions. Key electrical specifications include a typical quiescent current of 69µA at no load and 875µA at full load. Output noise is minimized to 30µVRMS with a bypass capacitor. The regulator features high power supply rejection ratios of 70dB at 1kHz and 40dB at 1MHz. It includes integrated thermal shutdown and current limiting protection.
