*1: "A" may be indicated to the right of the Sanken logo.
*2: VIN(max) and IO(max) are restricted by the relation PD(max)=(VIN-VO)•IO=18(W).
*3: Refer to the dropout voltage.(Refer to Setting DC Input Voltage on page 7.)
*4: IS1 is specified at –5(%) drop point of output voltage VO on the condition that VIN=VO+3V, IO=1A.
*5: A foldback type overcurrent protection circuit is built into the IC regulator. Therefore, 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
