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

Verify the specific suffix 'RTM' against official onsemi documentation to confirm tape-and-reel configuration details. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents. Ensure the part number matches the exact pinout and marking requirements for your PCB design before finalizing procurement orders.

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

Select this component when a fixed 3.3 V rail is required with moderate current demands up to 800 mA. Consider the TO-252-3 package for surface-mount assembly constraints. Evaluate the 15 V maximum input rating against your system's supply voltage to ensure adequate headroom without exceeding limits.
