Dropper Type Regulator with Output On/Off Control

SI-3001S

Notes:

*1. Since PD(max) =( VIN –VO)• IO = 18( W ), VIN(max) and IO(max) may be limited depending on operating

conditions. Refer to the Ta -PD curve to compute the corresponding values.

*2. Refer to the dropout voltage.

*3. IS1 rating shall be the point at which the output voltage VO (VIN = 14V, Io = 0.4A) drops to – 5%.

*4. The output control terminal Vc is pulled up inside the IC. Each input level can be directly driven with

LS-TTL ICs. Thus, LS-TTL direct driving is also possible.

a : Pre-regulator

b : Output ON/OFF control

c : Thermal protection

d : Over-input and overcurrent protection

e : Drive circuit

f : Error amplifier

g : Reference voltage

Co :

Output capacitor (47 to 100

µF, 50V)

C1, C2 : Anti-oscillation capacitors (C1: approx. 47

µF, C2: approx.

0.33

µF). These are required for inductive input lines or

long wiring. Tantalum capacitors are recommended for C1

and Co, especially at low temperatures.

D1 :

Protection diode. Required as protection against reverse

biasing between input and output.

(Recommended diode: Sanken EU2Z.)
