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

Verify that the specific part number suffix FDZW corresponds to the W-DFN2020-6 (SWP) Type A1 package configuration required for your PCB layout. Confirm the D suffix indicates the inclusion of the internal discharge resistor network. Ensure compliance with RoHS and halogen-free requirements if mandated by your assembly specifications.

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

Select this component when a fixed 2.8V rail is required with integrated output discharge capabilities. The W-DFN2020-6 package offers a compact footprint for dense layouts. Verify that the 300mA load current does not exceed thermal limits given the specific ambient conditions and copper area available on the board.

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

This device belongs to the AP7343Q family of low dropout regulators designed for automotive electronics. The series includes variants with different output voltages and packages. The 'D' designation specifically denotes the version equipped with an auto-discharge feature, distinguishing it from standard versions lacking this function.

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

What is the function of the 'D' suffix in the part number?

The 'D' suffix indicates that the regulator includes an integrated N-channel auto-discharge resistor to rapidly pull down the output voltage when the enable pin is deactivated.

How should the exposed pad be handled in the W-DFN2020-6 package?

The datasheet recommends connecting the exposed pad to ground or leaving it open, but advises using a large copper area for thermal dissipation rather than relying on it solely as a ground electrode.
