■Features

• Compact full-mold package (equivalent to TO220)

• Output current: 1.5A

• Low dropout voltage: VDIF≤1V (at IO=1.5A)

• Variable output voltage (rise only)
May be used for remote sensing

• Output ON/OFF control terminal is compatible with LS-TTL. (It may be
directly driven by LS-TTL or standard CMOS logic.)

• Built-in foldback overcurrent (SI-3033C: Drooping type overcurrent), ov­ervoltage, thermal protection circuits

■Applications

• For stabilization of the secondary stage of switching power supplies

• Electronic equipment

■Electrical Characteristics

*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=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: A foldback type ov ercurrent protection circuit is built into the IC regulator (e xcluding SI-3033C). Therefore, avoid using it for the follo wing applica-

tions as it may cause starting errors:
(1) Constant current load (2) Plus/minus power (3) Series power (4) VO adjustment by raising ground voltage
