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

Verify the specific suffix E2 indicates compliance with RoHS directives and lead-free manufacturing standards as per ROHM specifications. Confirm the HTSOP-J8 package dimensions match your PCB footprint requirements. Ensure input voltage does not exceed the 26.5 V maximum rating to prevent device failure. Check for any specific handling precautions related to the surface-mount technology used.

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

Select this component when a fixed 3.3 V output at 1 A is required with high input voltage tolerance up to 26.5 V. The low dropout characteristic makes it suitable for applications where the input voltage is close to the output voltage. Consider the thermal performance in the HTSOP-J8 package if operating near maximum current limits or in high ambient temperatures.
