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

Verify the specific suffix 'WR' corresponds to the SOT-25 package configuration before ordering. Confirm that the required output voltage matches the fixed 3.6V specification. Ensure the application environment operates within the specified ambient temperature range of -40°C to +85°C. Check for compliance requirements regarding RoHS and halogen-free standards if applicable to the final product assembly.

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

Select this component when a stable 3.6V rail is needed from a high-voltage source up to 45V. The low quiescent current makes it suitable for battery-operated systems requiring extended standby life. Verify that the expected load current does not exceed 300mA. Consider the SOT-25 package size constraints and thermal dissipation requirements based on the voltage drop across the device.
