AN6540
4-pin Voltage Regulator with Adjustable Rise Time
s Overview
The AN6540 is an integrated circuit designed for a 4-
pin voltage regulator with adjustable rise time. An exter-
nal 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 dif-
ference 0.3V(typ.).
