TECHNICAL DATA
3 TERMINAL LOW DROP OUTPUT
VOLTAGE REGULATOR
The KIA78D×× Series are fixed positive output low dropout
type, 3-pin voltage regulators with positive outout.
These regulators are used to provide a stabilized output voltage from
a fluctuating DC input voltage.
These are 12 fixed output voltage, as follows ; 2.5V, 3.3V, 3.5V,
5V, 6V, 8V, 9V, 10V, 12V, and 15V.
The maximum current capacity is 1A for each of the above voltage.
