Quiescent current is 1.2 mA typical, a figure that sets the standby power floor for always-on domains in the system. The single regulator channel with Enable and Soft Start control features supports power sequencing — the Enable pin gates the output, and Soft Start limits inrush current during startup, reducing stress on the upstream supply. ## Industrial temperature grade and protection suite The protection set includes Over Current, Over Temperature, and Short Circuit — the thermal shutdown prevents die damage during sustained overload, while current limiting folds back the output during a hard short. The 8-SOIC package with exposed pad (supplier device package 8-HTSOP-J) requires a thermal land on the PCB to conduct heat into the board plane. The exposed paddle is the primary thermal path — without a soldered connection to a copper pour, the junction-to-ambient thermal resistance rises significantly, and the 500 mA output capability may be thermally limited at the high end of the temperature range.","metaTitle":"BD18GA5MEFJ-LBH2 ROHM LDO, 1.8V Fixed Output, 500mA","metaDescription":"ROHM BD18GA5MEFJ-LBH2 LDO regulator, 1.8V fixed output, 500mA, 8-SOIC exposed pad.
