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
