BD33GA3VEFJ-ME2

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

The BD33GA3VEFJ-ME2 is a high-accuracy low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor, designed for automotive applications. It provides a fixed positive output voltage of 3.3 V with a maximum output current of 300 mA. The device operates within an input voltage range of 4.5 V to 14 V and supports an extended operating temperature range from -40°C to +105°C. Key electrical characteristics include a typical dropout voltage of 0.6 V at full load and a circuit current of 0.6 mA. The regulator is housed in an HTSOP-J8 surface-mount package.
