BDJ0GA3MEFJ-LBH2

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

The BDJ0GA3MEFJ-LBH2 is a single-output fixed linear voltage regulator (LDO) manufactured by ROHM Semiconductor. It provides a fixed output voltage of 10 V with a maximum output current of 300 mA. The device operates within an input voltage range of 4.5 V to 15 V and features a typical dropout voltage of 600 mV at full load, with a maximum of 900 mV. It includes a shutdown function, thermal shutdown protection, and overcurrent protection. The component is qualified under AEC-Q100 standards for automotive applications and operates within a temperature range of -40°C to +105°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the exact suffix LBH2 against official ROHM documentation to confirm package and tape specifications. Confirm AEC-Q100 qualification status directly from the datasheet. Ensure design-in compliance with automotive functional safety requirements if applicable. Cross-reference part numbers carefully as suffixes may indicate minor packaging or testing variations without changing electrical function.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 10 V output is required with 300 mA capability in automotive-grade environments. Consider the 15 V maximum input voltage limit and the 600 mV typical dropout voltage for headroom calculations. Evaluate the HTSOP-J8 package constraints for thermal dissipation and PCB layout. Compare against adjustable variants if flexible output voltages are needed instead of fixed regulation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context
