BD50HA5VEFJ-ME2

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

The BD50HA5VEFJ-ME2 is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor, designed for automotive applications. It provides a stable 5 V output with a maximum current capacity of 500 mA. The device operates within an input voltage range of 4.5 V to 8 V and supports an extended operating temperature range from -40°C to +105°C. Key electrical specifications include a typical dropout voltage of 600 mV at full load, line regulation of 25 mV, and load regulation of 25 mV. The unit features high accuracy with ±1.0% output voltage tolerance at 25°C and includes integrated protection mechanisms such as thermal shutdown and over-current protection.
