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

Verify the specific suffix TR indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the ordering part number matches the exact voltage and package requirements. Check for any end-of-life or not-for-new-designations if applicable to long-term procurement planning.

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

Select this component when a fixed 1.5 V rail is required with moderate current demands up to 200 mA. The SSON004X1216 package suits space-constrained designs. Consider the 70 dB PSRR for noise-sensitive applications. Verify input voltage stays above 2.5 V to ensure proper regulation and dropout margin.
