Product Introduction

Overview

The LM2931ADT-5.0G is a positive fixed output low dropout (LDO) linear voltage regulator from onsemi. This device is part of the LM2931 series, which is designed to maintain proper regulation with an extremely low input-to-output voltage differential. It is capable of supplying output currents in excess of 100 mA and features a low bias current of 0.4 mA at 10 mA output. The LM2931ADT-5.0G is specifically designed to survive in harsh automotive environments and protects external load circuitry from various input fault conditions, including reverse battery connection, two battery jump starts, and excessive line transients during load dump. It also includes internal current limiting, thermal shutdown, and temporary mirror-image protection.

  • Ability to withstand temporary power-up with mirror-image insertion.
  • Protection against input fault conditions such as reverse battery connection, two battery jump starts, and excessive line transients during load dump.
  • High accuracy output voltage with a tolerance of ±3.80%.
  • Available in various packages including SOIC-8, DPAK, D2PAK, TO-220, and TO-92.
  • Ultra-high power supply rejection ratio (PSRR) for stable output voltage.

Applications

  • Battery-powered consumer products.
  • Handheld instruments.
  • Automotive systems requiring robust voltage regulation and protection.
  • Industrial equipment where low dropout voltage and high current capability are necessary.
