sStandard External Circuit
C0
: Output capacitor (Approx. 200
µF)
*1 C1
: Oscillation prevention capacitor (C1: Approx. 47
µF)
The distance between terminals No.5 (VIN) and No.1 (GND)
must be made as short as possible. If the input line is induc-
tive or in the case of long wiring, a capacitor of approxi-
mately 0.33
µF with superior high frequency characteristics
must be connected in parallel. Tantalum capacitors are rec-
ommended for C1 and C0, particularly at low temperatures.
*2 CDLY : Delay capacitor (reset output)
*3 R1
: Pull-up resistor (300
Ω or above)
*4 D1
: Protection diodes
These diodes are required for protection against reverse
biasing of the input and output. Sanken EU2Z is recom-
mended.
