BD70HA3MEFJ-LBH2

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

The BD70HA3MEFJ-LBH2 is a fixed-output linear low-dropout regulator manufactured by Rohm Semiconductor. It provides a stable 7V output with a maximum continuous current of 300mA. The device operates within an input voltage range up to 8V and features a typical dropout voltage of 600mV at full load, reaching a maximum of 1.2V. Designed for surface-mount installation in an 8-HTSOP-J package with a bare pad, it supports an operating temperature range from -40°C to +105°C. Key electrical characteristics include a quiescent current of 1.2mA and integrated protection against overcurrent, thermal overload, and short circuits.
