BD30HA3MEFJ-LBH2

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

The BD30HA3MEFJ-LBH2 is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3.0V output with a maximum continuous current of 300mA. The device operates within an input voltage range of 4.5V to 8V and features a typical dropout voltage of 600mV at full load. Designed for industrial applications, it supports surface-mount installation in an HTSOP-J8 package. The component functions reliably across an extended temperature range from -40°C to +105°C.
