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

Verify that the specific part number suffix 'D' corresponds to the version with built-in active output discharge, as the standard AP7350 lacks this feature. Confirm the 'CF4' suffix matches the required X2-WLB0606-4 package type. Ensure the ordering quantity aligns with the manufacturer's standard packing quantity of 3,000 units per tape and reel. Cross-reference the datasheet revision to confirm electrical characteristics remain consistent with your design requirements.

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

Select this component when board space is limited due to its industry-minimum LDO footprint. Choose the AP7350D variant specifically if the application requires the output voltage to be actively discharged upon disabling the enable pin. This regulator is appropriate for systems requiring high output voltage accuracy and minimal standby power consumption. Ensure the load current does not exceed the guaranteed 150mA limit under all operating conditions.

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

This device belongs to the AP7350 series of ultra-low quiescent current LDO regulators from Diodes Incorporated. The series offers various fixed output voltages ranging from 1.2V to 4.5V. The 'D' designation indicates the inclusion of an internal discharge resistor, distinguishing it from the non-discharge AP7350 model. All variants share the same compact X2-WLB0606-4 package and core electrical specifications.
