BD12IC0VEFJ-ME2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BD12IC0VEFJ-ME2 is a positive fixed linear low-dropout (LDO) voltage regulator manufactured by Rohm Semiconductor. It provides a fixed output voltage of 1.2V with a maximum continuous output current of 1A. The device supports an input voltage range up to a maximum of 5.5V. Key electrical specifications include a maximum dropout voltage of 0.9V at full load and a typical quiescent current of 700 µA. It features integrated protection mechanisms including overcurrent, thermal shutdown, and short-circuit protection. The component is housed in an 8-HTSOP-J surface-mount package with exposed pad for enhanced thermal performance.
