LT1573 Overview

Key Features

  • When combined with an external PNP power transistor, this device provides load current up to 5A with dropout voltages as low as 0.35V
  • The LT1573 circuitry is designed for extremely fast transient response
  • This greatly reduces bulk storage capacitance when the regulator is used in applications with fast, high current load transients
  • Base drive is limited for instantaneous protection, and a time-delayed latch protects the regulator from continuous short circuits
  • Output accuracy is better than 1% to meet the critical regulation requirement of fast microprocessors
  • A special 8-pin, fused-lead surface mount package is used to minimize regulator footprint and provide adequate heat sinking
