5V/50mA regulator (always on, with reverse current flow prevention function).
10V/2000mA regulator (when used with an external 2SB921 PNP transistor) with standby function (on/off control).
Regulators (four for 8V systems and one 5V system) with on/off functions controlled by a shift resister/latch function. This IC also provides four open-collector output systems and two emitter-follower type output systems.
Full complement of built-in protection circuits.
