LR9284 Datasheet
  

ULTRALOW QUIESCENT CURRENT, 500mA, CMOS LINEAR REGULATOR

 

 

DESCRIPTION

 

The UTC LR9284 is a typical LDO (linear regulator) with the

features of high output voltage accuracy, ultralow supply current,

low ON-resistance. Internally, there’re many functions of UTC

LR9284 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 LR9284.

The output voltage of these ICs is fixed with high accuracy.

 

FEATURES

 

* Supply current (TYP=0.3µA)

* Output voltage accuracy (±1.5%)

* Input voltage range (2V~7V)

* Dropout voltage (TYP=220mV @ 200mA, VOUT=3.3V)

* Line regulation (TYP=0.1%/V)

* Built-in fold-back protection circuit (TYP=90mA) (Current at short mode)
