Datasheet Summary
UNISONIC TECHNOLOGIES CO., LTD
LOW NOISE 300mA LDO REGULATOR
- DESCRIPTION
The UTC LR9133 is a typical LDO (linear regulator) with the Features of high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection.
During operation of the UTC LR9133, the dropout voltage is very low and the response of line transient and load transient are very well.
Internally, there’re many functions of UTC LR9133 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 LR9133.
The UTC LR9133 can be used as an ideal of the power supply...
