LM2931A - Low Dropout Voltage Regulator

General Description

LM2931A is a fixed 3-terminal low dropout voltage regulator designed to need very low quiescent current.

Internally, implemented circuits include 60V load dump protection, -50V reverse transient short circuit and thermal over load protection.

Key Features

  • Limited input voltage and high efficiency. Internal thermal over load protection. 60V load dump protection. Output current up to 0.1A.
