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

Verify the specific ordering suffix to confirm the presence of the internal discharge feature, as indicated by the 'D' designation in the part number. Ensure compatibility with RoHS3 and REACH standards if required by your manufacturing environment. Confirm that the X2-DFN1010-4 package dimensions align with your PCB footprint design guidelines before finalizing procurement.

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

Select this component when a low 1.1V rail is required for portable electronics. Consider the 300mA current limit and the specific dropout voltage characteristics at varying load currents. Evaluate the need for the auto-discharge function provided by the 'D' variant versus standard versions. Ensure input voltage remains above the minimum threshold while accounting for dropout requirements across the full operating temperature range.

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

This device belongs to the AP7341 series of low dropout regulators from Diodes Incorporated. The series is characterized by high accuracy, low on-resistance, and low quiescent current. The AP7341D variant specifically includes an integrated N-channel auto-discharge feature on the output when disabled, distinguishing it from non-discharge versions within the same family.
