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

Verify the manufacturer designation as Texas Instruments for the NOPB suffix variant. Confirm the package type is SOT-23-5 and the output voltage is strictly 2.5 V. Ensure the component meets the specified operating temperature range of -40°C to +125°C. Cross-reference the datasheet for line regulation and load regulation specifications before integration.

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

Select this component when a fixed 2.5 V output is required with high input voltage tolerance up to 16 V. It is suitable for applications needing 100 mA load current with minimal voltage drop. Consider the SOT-23-5 footprint for space-constrained designs. Verify thermal performance under maximum load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the LP2981 series of LDO regulators. It shares features with other variants like LP2981IM5X-2.9 and LP2981IM5X-5.0, differing primarily in fixed output voltage. The series is known for low noise and high PSRR, suitable for sensitive analog circuits.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

LP2981IM5X-2.9/NOPB offers similar characteristics with a 2.9 V output. LP2981IM5X-5.0 provides a 5 V fixed output. Both share the same package and electrical limits, allowing potential substitution if voltage requirements differ.
