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

Verify the specific suffix 'WR' corresponds to the required SOT25 pinout configuration, as other variants like W5 or WW exist within the same series. Confirm that the 150mA output current rating aligns with the peak load requirements of the target circuit design. Ensure compliance with RoHS 3 and REACH standards if applicable to the manufacturing region. Validate that the 30V maximum input voltage exceeds the system's highest potential supply rail under all operating conditions.

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

Select this component when a fixed 5V output is required alongside high input voltage tolerance up to 30V. The WR package designation indicates a specific pin arrangement within the SOT25 footprint; verify pin compatibility against existing board layouts compared to W5 or WW packages. Consider the 150mA current limit for loads approaching this threshold, noting that dropout voltage increases significantly at higher currents. Evaluate the need for the enable pin functionality available in this package type versus non-enable versions.
