The application of the board is to let a user evaluate the performance of the BD7xxL2EFJ/FP/FP3-CE2 LDO. The purpose of the EVK is to allow the test and evaluation of the LDO IC in professional research and development environments. This document provides guidelines to quickly setup the hardware for fast and easy LDO IC performance evaluation. For further details about the LDO ICs and other ROHM products, please also consult the relevant product datasheets and general information at http://www.rohm.com. 1.1 Operating instructions A block diagram of the EVK application is depicted in Figure 1. In order to evaluate the board apply input voltage, connect the DC load and measure the output voltage of the LDO. Note: when connecting laboratory equipment and other peripherals do not use cables with length more than 3 meters due to EMC compliance. Figure 1: EVK operating block diagram 1.2 Electrical Parameters / EVK Model Overview This LDO EVK has 6 different model variants. The main difference between the variants is the package of the LDO and output voltage level. Table 1 gives an overview of the different IC features and the according naming of the EVK.

Safety Instructions 3.1 Warnings      This product should be operated in a well ventilated environment and, if used inside a case, the case should not be covered. This product should be placed on a stable, flat, non-conductive surface in use and should not be contacted by conductive items. All peripherals used with the EVK should comply with relevant standards for the country of use and be marked accordingly to ensure that safety and performance requirements are met. Where peripherals are connected that do not include the cable or connector, the cable or connector used must offer adequate insulation and operation in order that the requirements of the relevant performance and safety are met. The connection of incompatible devices to the EVK may affect compliance or result in damage to the unit and invalidate the warranty. 3.2 Instructions for Safe Use     Do not expose it to water, moisture or place on a conductive surface whilst in operation. Do not expose it to temperatures, which are out of the operational range specified for hardware and components populating the EVK. Take care whilst handling to avoid mechanical or electrical damage to the printed circuit board and components Avoid handling the printed circuit board while it is powered. Only handle by the edges to minimize the risk of electrostatic discharge damage. www.rohm.com © 2016 ROHM Co., Ltd.
