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

Verify that the specific part number suffix FS4 corresponds to the X2-DFN1010-4 package type required for your PCB layout. Confirm the absence of the 'D' suffix, which indicates an integrated output discharge feature not present in this non-discharge variant. Ensure compatibility with RoHS 3 compliance standards if applicable to your manufacturing requirements.

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

Select this component when a fixed 1.8V rail is needed with minimal static power consumption. The X2-DFN1010-4 package offers a compact footprint suitable for space-constrained designs. Consider the 150mA current limit and ensure the application load remains within this boundary to maintain regulation stability.

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

Does the AP7354-18FS4-7 include an internal output discharge resistor?

No, the AP7354-18FS4-7 does not have an internal output discharge resistor. This feature is only available in the AP7354D variant.

What is the function of the EN pin on this device?

The EN pin serves as the chip enable control. Driving it high turns the regulator on, while pulling it low places the device into shutdown mode.
