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

Verify the specific ordering suffix 'E' confirms the inclusion of the delay pin feature for inrush current control. Confirm the package type matches the required board layout constraints for the DFN(PL)1820-6 footprint. Ensure external capacitor values meet stability requirements based on the selected output voltage.

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

Select this variant when adjustable inrush current limiting is required via the DELAY pin. Compare against B/D versions if delay functionality is unnecessary. Verify that the DFN(PL)1820-6 package suits the thermal and spatial requirements of the target design compared to SOT-89-5 or HSOP-6J options.

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

This component belongs to the RP132x series of low voltage 1A LDO regulators. The series offers both fixed and adjustable output voltage types across multiple package formats including DFN, SOT-89, HSOP, and TO-252.
