RH1573K DICE Low Dropout PNP Regulator Driver
DESCRIPTION ABSOLUTE MAXIMUM RATINGS (Note 1)
The RH1573 is a regulator driver IC designed to provide a Input Pin Voltage (VIN to GND) ...10V solution for applications requiring high current, low dropout Drive Pin Voltage (VDRIVE to GND) ..10V and fast transient response. When driving an external PNP Output Pin Voltage (VOUT to GND) ..10V power transistor, this device provides load current up to Shutdown Pin Voltage (VSHDN to GND) ...10V 5A with a dropout voltage as low as 0.35V. The RH1573 Operating Junction Temperature circuitry is designed for extremely fast transient response. Range .. –55°C to 125°C This greatly reduces bulk storage capacitance when the Storage Temperature Range ... –65°C to 150°C regulator is used in applications with fast, high current load transients. The RH1573 uses a time-delayed latching L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation. overcurrent protection technique that requires no external All other trademarks are the property of their respective owners. sense resistor. Base drive is limited for instantaneous protection, and a time-delayed latch protects the regulator from continuous short circuits. rh1573kdicef 1
