*1: VIN(max) and IO(max) are restricted by the relation PD(max)=(VIN-VO)•IO=20(W).
*2: Refer to the dropout voltage.(Refer to Setting DC Input Voltage on page 7.)
*3: IS1 is specified at –5(%) drop point of output voltage VO on the condition that VIN=VO+3V, IO=1.0A.
*4: A f oldbac k type o v ercurrent protection circuit is b uilt into the IC regulator. Theref ore, avoid using it for the following applications as it may cause
starting errors:
(1) Constant current load (2) Plus/minus power (3) Series power (4)VO adjustment by raising ground voltage
