Panasonic AN6540 Datasheet
AN6540
4-pin Voltage Regulator with Adjustable Rise Time
■ Overview
The AN6540 is an integrated circuit designed for a 4pin voltage regula tor with adjustable rise time. An external capacitor allows any setting of output v oltage 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.).
■ Features
• Low dropout voltage:0.3V(typ.)
• Control of output voltage rise time
• Internal short-circuit protection
• Low temperature coefficient of output voltage
