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

Verify the specific suffix ME2 against the official ROHM datasheet to confirm pinout and electrical characteristics match your design requirements. Confirm availability status as this component may be subject to end-of-life notices or limited production runs. Ensure the HTSOP-J8 package footprint aligns with your PCB layout constraints before finalizing procurement orders.

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

Select this regulator when a stable 1.5 V rail is required for automotive loads with currents up to 300 mA. Consider the 600 mV typical dropout voltage to ensure sufficient input-to-output differential under all load conditions. Verify that the 8 V maximum input voltage rating accommodates the highest expected bus voltage transients in the target automotive application without exceeding absolute maximum ratings.
