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

Verify the part number suffix 'SNG' corresponds to the DFN2020-6 package and '33' indicates the fixed 3.3V output. Confirm RoHS compliance status and ensure the supplier provides original manufacturer documentation. Check for any specific handling requirements related to the surface mount package type during assembly.

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

Select this component when a fixed 3.3V rail is required with minimal external components. It is suitable for applications prioritizing low standby power consumption due to its 35µA quiescent current. Ensure the input voltage remains within the 2V to 6V range and that the thermal design accommodates the expected power dissipation at full load.

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

This part belongs to the AP7335 series of low dropout regulators from Diodes Incorporated. The series offers both adjustable and fixed output versions in SOT25 and DFN2020-6 packages. The AP7335-33SNG-7 specifically denotes the fixed 3.3V variant in the smaller DFN2020-6 footprint, designed for space-constrained portable electronics.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct replacements include other AP7335 variants with different output voltages or packages, such as AP7335-XXWG-7 for SOT25 packaging. Cross-brand equivalents require matching electrical specifications including 300mA output current, 3.3V fixed output, and compatible package dimensions.
