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

Verify the specific suffix ME2 against official ROHM documentation to confirm package type and tape-and-reel specifications. Confirm AEC-Q100 qualification status directly from the manufacturer datasheet before integration into safety-critical designs. Ensure input voltage constraints are strictly observed to maintain regulation accuracy and prevent thermal issues.

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

Select this component when a fixed 1 V output is required for automotive environments with limited space due to the compact HTSOP-J8 package. Consider the 500 mA current limit and 400 mV dropout voltage when designing the power rail. Verify that the application does not require adjustable output or higher current capabilities, which would necessitate different series models.

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

This part belongs to the BDxxIA5VEFJ series of automotive LDO regulators from ROHM. These devices are engineered for high reliability in harsh automotive environments.
