BD30HC0MEFJ-ME2

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

The BD30HC0MEFJ-ME2 is a single-output positive fixed linear voltage regulator (LDO) from ROHM Semiconductor, designed for automotive applications. It provides a 1 A output current with a typical dropout voltage of 0.6 V at full load. The device operates within an input voltage range of 4.5 V to 8 V and delivers a fixed output voltage with ±1.0% accuracy at 25°C. It features a load regulation of 25 mV and ripple rejection of 60 dB. The component supports an operating temperature range from -40°C to +105°C and includes built-in over-current protection (OCP), thermal shutdown (TSD), and soft-start functionality.

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

Verify the specific suffix ME2 against the official datasheet to confirm package type and tape/reel specifications. Confirm AEC-Q100 qualification status for your target automotive application tier. Check for end-of-life or not-recommended-for-new-designations if sourcing for new products. Ensure compatibility with HTSOP-J8 footprint requirements in your PCB layout.

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

Select this LDO when a fixed 1 A output with high accuracy is required in automotive environments. Consider its 0.6 V dropout voltage for efficiency under varying input conditions. Evaluate the need for integrated protection features like OCP and TSD to simplify external circuitry. Verify that the 8 V maximum input voltage aligns with your system's supply rails.
