LOW NOISE 300mA LDO
REGULATOR
DESCRIPTION
The UTC LR9101 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 LR9101, 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 LR9101 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 LR9101.
The UTC LR9101 can be used as an ideal of the power supply for hand-held communication equipment, such as: power source for portable communication equipment, power source for electrical appliances, for example, cameras, VCRs and camcorders and power source for battery-powered equipment.
