LR9500数据手册UTC中文资料规格书

描述 Description

The LR9500 is a linear regulator capable of supplying 150 mA output current. Designed to meet the requirements of RF/Analog circuits, the LR9500 device provides low noise, high PSRR, low quiescent current, and low line transient response figures. Usingnew innovative design techniques the LR9500 offers class-leading device noise performance without a noise bypass capacitor. The device is designed to work with 0.47 μF input and output ceramic capacitors. (No Bypass Capacitor is required) This device is available with 1.5V, 1.8V, 2.0V, 2.5V, 2.7V, 2.8V, 3.0V, 3.3V, 4.0V and 4.5V outputs. Please contact your local sales office for any other voltage options.
