LP5904 - Ultra Low Noise, 200mA Linear Regulator for RF/Analog Circuits Requires No Bypass Capacitor - 单通道LDO - 线性稳压器(LDO) - TI公司（Texas Instruments，德州仪器）
The LP5904 is a linear regulator capable of supplying 200 mA output current. Designed to meet the requirements of RF/ Analog circuits, the LP5904 device provides low noise, high PSRR, low quiescent current, and low line transient response figures. Using new innovative design techniques the LP5904 offers class-leading device noise performance without a noise bypass capacitor and the ability for remote output capacitor placement. An active pulldown circuit with a 280Ω resistor is wired from the output to ground pins to quickly discharge output when the device is disabled (VEN = low).
The device is designed to work with a 1.0 µF input and a 1.0 µF output ceramic capacitor. (No Bypass Capacitor is required.)
The device is available in a DSBGA package. For other package options contact your local TI sales office.
This device is available between 1.2V and 4.4V in 25 mV steps. Please contact Texas Instruments Sales for specific voltage option needs.
