The LP5900 linear regulator is capable of delivering 150mA of output current. The LP5900 device is designed to meet the requirements of RF/analog circuitry, providing low noise, high PSRR, low quiescent current, and low line transient response digital. Using a new innovative design technology, the LP5900 delivers noise-free bypass capacitor-class leading device noise performance. The device is designed to work 0.47μF input and output ceramic capacitors down to the size of the 0603 component.
The device is available in a micro SMD package and LLP package. This device can be used with 1.5V, 1.8V, 2.0V, 2.2V, 2.5V, 2.6V, 2.7V, 2.8V, 3.0V and 3.3V outputs.
The purpose of this evaluation board is to enable the evaluation of the LP5900 regulator. Each board assembly and test plant. The EV kit is available in a 6-pin LLP package.
