CMOS IC
HIGH VOLTAGE , ULTRA LOW
IQ VOLTAGE REGULATOR
DESCRIPTION
The UTC
UR78XX
Series are a low dropout regulator with wide
input voltage range, high output voltage accuracy, ultra low
quiescent current and low dropout. This regulator is based on a
CMOS process, and it’s input voltage could high enough more than
36V, thus they are very suitable for high voltage application.
FEATURES
* High output voltage accuracy: ±2%
* Ultra low quiescent current: 1.2uA (Typ.)
* Low temperature-drift coefficient of V
OUT
: ±50ppm/°C (Typ.)
* Wide Input voltage range: 0 ~ 36V
