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

Verify the exact part number suffix against official ROHM documentation to confirm pinout and electrical characteristics. Ensure compatibility with HTSOP-J8 surface-mount packaging requirements. Confirm that the application design accounts for the specified power dissipation limits and operating temperature range of -25°C to +85°C. Cross-reference datasheet revisions to avoid discrepancies in parameter values.

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

Select this component when a fixed 10 V output is required with moderate current capability up to 0.5 A. It is appropriate for designs prioritizing high accuracy and built-in protection features over adjustable output flexibility. Consider the thermal performance in the HTSOP-J8 package under maximum load conditions. Verify that the input voltage remains within the 4.5 V to 14 V operational window for proper regulation.
