LP5990TM-2.8EV

User's Guide SNVA219A – June 2007 – Revised April 2013 AN-1584 LP5990 DSBGA Evaluation Board 1 Introduction This board is designed to allow the evaluation of the LP5990 Low Voltage CMOS Regulator. Each board is pre-assembled and tested in the factory. The board contains the LP5990 in a 4 bump DSBGA, 0.4mm pitch package with input and output capacitors connected to GND . The LP5990 will provide a 1.8V regulated output from a low input voltage of 2.2V and can provide 200mA to an external load. The LP5990 is suitable for powering digital circuits, where good transient behavior is required. The LP5990 is designed to be stable with space saving 0402 capacitors as small as 1µF. 2 Operation The input voltage, applied between VIN and GND should be at least 1.0V above the output voltage with a maximum of 5.5V. Input connections should be kept reasonably short (
