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.

Co : Output capacitor (47 to 100µF, 50V)
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.
D1 : Protection diode. Required as protection against reverse
biasing between input and output.
(Recommended diode: Sanken EU2Z.)
