Panasonic AN6541 Datasheet
AN6541
3-pin Positive Voltage Regulator
■ Overview
The AN6541 is a 3-pin 9V voltage regulator which performs stable operations up to the minimum input/output
voltage diff erence 0.3V (typ.). Stabilized fixed output voltage is obtained from unstable DC input voltage.
The AN6541 can be used in power circuits with current
capacitance up to 300mA.
■ Features
• Low drop-out voltage:0.3V (typ.)
• Internal short-circuit current protection
• Low temperature coefficient of output voltage
