Product Description
The GLF1531Q is an ultra-efficiency integrated N- channel power protection switch, with a wide input range from 0.8 V to 5.5 V.


The GLF1531Q provides the programmable output voltage (VOUT) rise time by an external capacitor on the SR pin. It limits the inrush current at start up condition and helps to minimize the voltage drop. The integrated output discharge FET discharges output voltage quickly when the device is disabled.


The GLF1531Q offers the best-in-class on the size, on-resistance (RON) performance, and the wide operating temp range up to 125 °C.
