Pin description
Pin n° Symbol Note
1 SHDN
Shutdown input disables the regulator when it is connected to GND or to a positive
voltage lower than 0.6 V
2GND
Ground pin: internally connected to the die attach flag to decrease the total thermal
resistance and increase the package ability to dissipate power
3 Bypass Bypass pin: 0.1 µF bypass to improve the
thermal noise performance
4 OUT Output port
5 IN Input port
