LP2981-28DBVRG4

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

The LP2981-28DBVRG4 is a fixed-output, positive low-dropout regulator delivering 100 mA. It provides a nominal output voltage of 2.8 V with standard grade tolerance of ±1.25%. The device operates with an input voltage range from 2.2 V to 16 V and features ultra-low dropout, typically 200 mV at full load. Quiescent current is 600 μA at full load, dropping to 0.01 μA in shutdown mode. Integrated protections include overcurrent limiting and thermal shutdown.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Ultra-low dropout performance utilizing a vertical PNP pass element for efficient power management.
Integrated shutdown control via the ON/OFF pin enables deep sleep currents for battery conservation.
Built-in overcurrent and thermal protection safeguards against short circuits and overheating.
