LR4XXYY中文资料Dual，Low-Noise，200mA LDO  REGULATOR数据手册UTC规格书

描述 Description

The UTC LR4XXYY are dual voltage regulator ICs that have high output voltage accuracy, low dropout, low supply current, and high ripple rejection. Every Channel of UTC LR4XXYY seriesconsists of a voltage reference unit and over temperature protection, simultaneity; also consists of an error amplifier, a current limit circuit, resistors for setting output voltage, and a chip enable circuit, respectively. The EN1 and EN2 pins control each output respectively, When both outputs shutdown simultaneously, the chip will be turn off and consumes nearly zero operation current which is suitable for battery-power devices. The load transient response and line transient response of the UTC LR4XXYY Series are excellent, so these ICs are suitable for hand-held communication equipment power supply.
