BD15HA5VEFJ-ME2

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

The BD15HA5VEFJ-ME2 is a positive low-dropout linear regulator manufactured by ROHM Semiconductor. It provides a fixed 1.5 V output with a maximum continuous current of 500 mA. The device operates within an input voltage range of 4.5 V to 8 V and maintains performance across an extended temperature range from -40 °C to +105 °C. Key electrical characteristics include a typical dropout voltage of 600 mV, with a maximum limit of 900 mV. Line regulation and load regulation are specified at 25 mV each. The component is housed in an HTSOP-J8 surface-mount package suitable for automotive applications.
