BD90GC0JEFJ-E2

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

The BD90GC0JEFJ-E2 is a positive fixed-output low-dropout (LDO) regulator manufactured by ROHM Semiconductor. It provides a stable 9.0 V output with a maximum current capacity of 1 A. The device supports an input voltage range up to 15 V and operates within a temperature range of -25°C to +85°C. Key electrical specifications include a typical dropout voltage of 600 mV at full load, a line regulation of 20 mV, and a reference voltage of 750 mV. The IC features built-in overcurrent protection, thermal shutdown, and a shutdown function that reduces standby current to near zero.
