*2. Refer to the dropout voltage.
*3. I
S1
rating shall be the point at which the output voltage V
O
(V
IN
= 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
