LP5900SD-3.0EV
用于射频模拟电路的超低噪声、150mA 线性稳压器，无需旁路电容器
LP5900SD-3.0EV
概述
The LP5900 is a linear regulator capable of supplying 150mA output current. Designed to meet the requirements of RF/Analog circuits, the LP5900 device provides low noise, high PSRR, low quiescent current, and low line transient response figures. Using new innovative design techniques the LP5900 offers class-leading device noise performance without a noise bypass capacitor. The device is designed to work with 0.47µF input and output ceramic capacitors down to 0603 component size.
The device is available in a micro SMD package and a LLP package. This device is available with 1.5V, 1.8V, 2.0V, 2.2V, 2.5V, 2.6V, 2.7V, 2.8V, 3.0V, and 3.3V outputs.
This evaluation board is designed to enable the evaluation of the LP5900 Voltage Regulator. Each board is assembled and tested in the factory. This evaluation board has the 6 pin LLP package mounted.
