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

Verify the specific ordering suffix U5T1U3 corresponds to the SOT-89-5 tape packaging and lead-free/halogen-free environmental compliance. Confirm that the D-type designation matches the requirement for unavailable discharge shunt and pull-down resistor functions. Ensure application design accounts for thermal dissipation limits when operating near maximum output currents.

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

Select this component for applications requiring a fixed 2.2 V rail with high current capability. The D-type variant is suitable where discharge shunt and pull-down resistor functions are not required. Verify that input and output ceramic capacitors meet the minimum 2.2 μF requirement for stability. Consider thermal resistance values based on the PCB layout when designing for high load conditions.

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

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the function status of the discharge shunt and pull-down resistor for the S-13A1Dxx series?

For the S-13A1Dxx series, both the discharge shunt function and the pull-down resistor are unavailable.

How is the inrush current limit time adjusted for internally set output voltage types?

The inrush current limit time can be adjusted by connecting an external capacitor (CSS) between the SSC pin and the VSS pin.
