产品详情

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 the output capacitance requirements 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.
