Pinout and package

(Top View)
(Top View)
Package: TSOP-5 (Pb-Free)
PinNameFunctionSource
1IN, Input pin. A small capacitor is needed from this pin to ground to assure stability.
2GND, Power supply ground.
3EN, Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown mode.
4N/C, Not connected. This pin can be tied to ground to improve thermal dissipation.
5OUT, Regulated output voltage pin. A small ceramic capacitor with minimum value of 1 μF is needed from this pin to ground to assure stability.
