The UTC
LR1012
series is high operating voltage regulator
using UTC CMOS technology. The max operating voltage of UTC
LR1012L
is 16V so it works best in high-voltage applications.
Moreover, it is also suitable in constructing lowpower portable
devices including small current consumption, power-off function
and short-current protection.

TERMS
CMOS IC
C
L
(Output capacitors)
Cause the UTC
LR1012L
series can provide stable operation without C
L
.So the C
L
are used only to improve
transient response characteristics.And when C
L
is used, a low ESR (Equivalent Series Resistance) capacitor like
ceramic capacitor can also be used. C
L
can hence be removed in applications when transient response can be
negligible.
V
OUT
(Output voltage)
Unless the under conditions change, the accuracy of the output voltage is ±2.0% guaranteed under the specified
conditions for input voltage, which differs depending upon the product items, output current, and temperature.
∆V
OUT1
,
∆V
OU
T2 (Line regulations 1 and 2)
After a change in the input voltage with the output current remained unchanged, these values show how much
the output voltage changes.
∆V

3 (Load regulation)
After a change in the output current with the input voltage remained unchanged, these values show how much
the output voltage changes.
Dropout voltage (Vdrop)
When output voltage falls to 98% of V
OUT
(E) by gradually decreasing the input voltage (V
IN),
this value shows the
difference between the input voltage (V
