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

Verify the specific product type suffix 'C' to confirm the presence of the discharge shunt function and constant current source pull-down feature, as these vary across the series. Confirm the package designation 'M5T1' corresponds to the SOT-23-5 form factor. Ensure compliance with environmental codes such as lead-free and halogen-free status before integration.

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

Select this model for applications requiring a fixed 3.5 V output with high accuracy. Consider the C-type configuration if internal discharge and pull-down functions are required. Evaluate thermal dissipation constraints, as power limits depend on ambient temperature and board mounting conditions. Verify that input voltage remains within the specified 1.4 V to 5.5 V range during operation.
