LP5951MF-2.5EV

User's Guide SNVA169C – September 2006 – Revised April 2013 AN-1486 LP5951 Evaluation Board 1 Introduction This evaluation board is designed to enable independent evaluation of the LP5951 electrical performance. Each board is pre-assembled and tested in the factory. The evaluation kits are available in two options: LP5951MF-1.8EV and LP5951MF-2.5EV. For other voltage and package options, the device can be ordered from LP5951 product folder on TI's website. The board offers two different assembly options: SC70-5 package (MG) on top side (TOP) or SOT23-5 package on bottom side (BOT) of the board. Only one side will be assembled at a time. 2 General Description The LP5951 converts high input voltages to lower output voltages while consuming low quiescent current. The LP5951 is capable of operating with an input voltage range from 1.8 V to 5.5 V for fixed output voltage options from 1.3 V to 3.3 V. The LP5951 can supply a maximum output current of 150 mA and is particulary suitable for portable, battery-powered systems. It also features internal protection against shortcircuit currents and over-temperature conditions. The input voltage, applied between VIN and GND should be at least 0.35V above the output voltage to operate the device out of dropout with a minimum of 1.8 V and no higher than 5.5 V. Input connections should be kept reasonably short (
