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

Verify that the specific part number corresponds to the D-type configuration, which lacks a GO pin and relies on internal logic for mode switching. Confirm the USPN-4 package variant matches the design requirements. Ensure compliance with EU RoHS standards as indicated by the -G suffix. Review absolute maximum ratings regarding power dissipation limits before finalizing procurement specifications.

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

Select this component when a fixed 1.8V rail is required with minimal quiescent current consumption during light loads. The D-type designation indicates the absence of an external GO pin, simplifying board layout compared to A or B types. Consider the USPN-4 package dimensions for space-constrained applications. Verify that the input voltage remains above the minimum threshold to maintain regulation under all operating conditions.

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

How does the Green Operation function affect performance?

The Green Operation function automatically switches between High Speed mode for heavy loads and Power Save mode for light loads, optimizing efficiency and reducing supply current.

What is the purpose of the CL auto-discharge feature in the D type?

The CL auto-discharge feature rapidly discharges the output capacitor when the CE pin is pulled low, ensuring the output voltage quickly returns to the VSS level.
