LP2980AIM5-3.8/NOPB

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

The LP2980AIM5-3.8/NOPB is a fixed-output micropower ultra-low-dropout linear regulator manufactured by Texas Instruments. It provides a regulated 3.8 V output with a maximum load current of 50 mA and features an initial output voltage accuracy of ±0.5%. The device operates within a wide input voltage range from 2.1 V to 16 V and utilizes an optimized vertically integrated PNP process. Key electrical characteristics include a typical dropout voltage of 120 mV at full load, a ground pin current of 375 μA at 50 mA, and less than 1 μA quiescent current in shutdown mode. It incorporates overcurrent and overtemperature protection and requires only a 1-μF external capacitor for stability.
