PIN CONFIGURATION

The NJM2382 is a low voltage operation switching regulator

control IC.

It features totem pole output directly driving external bipolar

transistor and operates at high switching frequency which

improves transient response. In addition, low power standby

function is incorporated.

It is suitable for LCD back light, and other portable

applications.
