Notes:
*1. Since PD(max) = (VIN –V )• IO =18(W),
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 V (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.
Co :
Output capacitor (47 to 100µF, 50V)
V
IN
(max)and IO (max)may be limited depending on operating
O
C1, C2 : Anti-oscillation capacitors (C1: approx. 47µF, C2: approx.
0.33µF). These are required for inductive input lines or
long wiring. Tantalum capacitors are recommended for C1
and Co, especially at low temperatures.
O
D1
:
Protection diode. Required as protection against reverse
biasing between input and output.
(Recommended diode: Sanken EU2Z.)
