*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=0.5A. *4: 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. *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

: Output capacitor (47 to 100µF) : Oscillation prevention capacitor (C1: Approx. 47µF, C2: 0.33µF) These capacitors are required if the input line is inductive and in the case of long wiring. Tantalum capacitors are recommended for C1 and C0, particularly at low temperatures. : Protection diode This diode is required for protection against reverse biasing of the input and output. Sanken EU2Z is recommended.
