AN6540
4-pin Voltage Regulator with Adjustable Rise Time
s Overview
The AN6540 is an integrated circuit designed for a 4pin voltage regulator with adjustable rise time. An external capacitor allows any setting of output voltage rise time and noise reduction at power on, and are best suited for power circuits with current capacitance up to 240mA. It can be used up to the minimum input/output voltage difference 0.3V(typ.).
