L7809AB Overview

The L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, D²PAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shut-down and safe area protection,...

L7809AB Key Features

  • Output current up to 1.5 A
  • Thermal overload protection
  • Short circuit protection
  • Output transition SOA protection
  • 2 % output voltage tolerance (A version)
  • Guaranteed in extended temperature range (A version)
