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

Verify the exact part number suffix against official Torex documentation to confirm package type and output voltage. Ensure compatibility with your PCB footprint, specifically the USPN-4 package dimensions. Check RoHS compliance status if required by your manufacturing standards. Confirm thermal performance under your specific board layout conditions. Always refer to the latest datasheet for absolute maximum ratings and handling precautions.

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

Select this component when a fixed 2.5 V output is required with minimal quiescent current draw. The USPN-4 package is ideal for compact designs where SOT-25 alternatives do not fit. Consider the 200 mA current limit for moderate load applications. Evaluate the 95 mV dropout voltage against your minimum input voltage constraints. Compare PSRR specifications if noise immunity is critical for your signal chain.
