*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=14(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=0.5A.
*5: Output is ON even when output control terminal VC is open. Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an

LS-TTL circuit.
*6: When setting output voltage to 5V or less, input voltage needs to be set to 6V or over to operate stably.
*7: A foldbac k type overcurrent protection circuit is built into the IC regulator. Therefore, avoid using it for the follo wing applications as it ma y cause

starting errors:

(1) Constant current load (2) Plus/minus power (3) Series power (4) VO adjustment by raising ground voltage
