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

Verify the specific product type suffix 'C' confirms the absence of the discharge shunt function and presence of the pull-down resistor. Confirm the package designation 'M5T1' corresponds to the SOT-23-5 form factor. Ensure environmental code 'U' indicates lead-free and halogen-free compliance before finalizing procurement specifications.

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

Select this component when a fixed 1.5 V output is required with high accuracy. The C-type configuration is suitable if internal discharge shunt functionality is not needed but a pull-down resistor on the control pin is desired. Evaluate thermal dissipation constraints as the device includes thermal shutdown protection that activates at elevated junction temperatures.

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

This part belongs to the S-1333 Series of low dropout regulators developed using CMOS technology. The series offers selectable output voltages in 0.05 V steps ranging from 1.0 V to 3.5 V. The S-1333C variant specifically defines the internal logic functions regarding the ON/OFF pin controls, distinguishing it from A, B, and D types within the same family.
