DESCRIPTION

The UTC LR9282 is a typical LDO (linear regulator) with the
features of high output voltage accuracy, low supply current, low
ON-resistance. Internally, there’re many functions of UTC LR9282
which can be seen in the block figure. There are a voltage
reference unit, an error amplifier, resistor-net for voltage setting, a
current limit circuit, and a chip enable circuit in each UTC LR9282.
The output voltage of these ICs is fixed with high accuracy.

FEATURES

* Supply current (TYP=1µA)

* Dropout voltage (TYP=110mV )(IOUT=100mA 3.3V Output type)
* Line regulation (TYP=0.05%/V)
* Temperature-Drift Coefficient of Output Voltage  (TYP=±100ppm/°C)
* Built-in fold-back protection circuit (TYP=20mA)  (Current at short mode)
