BD90GA3WEFJ-E2

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

The BD90GA3WEFJ-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 9.0 V output with a maximum load current of 0.3 A. The device operates within an input voltage range of 4.5 V to 14 V and maintains a typical dropout voltage of 0.6 V at full load. Quiescent current is specified at 0.6 mA. It features ±1.0% output accuracy at 25°C and includes built-in overcurrent protection, thermal shutdown, and a shutdown function that reduces standby current to 0 µA. The component is housed in an HTSOP-J8 package suitable for surface mount applications.
