RH1573K DICE
Low Dropout PNP
Regulator Driver
DESCRIPTION ABSOLUTE MAXIMUM RATINGS The RH1573 is a regulator driver IC designed to provide a
solution for applications requiring high current, low dropout
and fast transient response. When driving an external PNP
power transistor, this device provides load current up to
5A with a dropout voltage as low as 0.35V. The RH1573
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. The RH1573 uses a time-delayed latching
overcurrent protection technique that requires no external
sense resistor. Base drive is limited for instantaneous
protection, and a time-delayed latch protects the regulator
from continuous short circuits. Input Pin Voltage (VIN to GND) .10V
