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

Verify that the specific part number suffix matches the required package type and output discharge configuration. Confirm compliance with RoHS standards and ensure the ordering quantity aligns with the manufacturer's standard tape and reel packaging specifications. Cross-reference the datasheet revision to confirm electrical characteristics match the design requirements.

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

Select this component when a fixed 4.5V rail is required with minimal static power consumption. Ensure the input voltage remains above the minimum threshold while accounting for dropout voltage at the expected load current. Verify that the thermal dissipation capabilities of the SOT-25 package are sufficient for the application's ambient temperature and power loss conditions.

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

This device belongs to the AP7354 series of ultra-low quiescent current LDO regulators. The series offers various fixed output voltages ranging from 1.1V to 4.5V. The 'W5' suffix indicates the SOT-25 package variant, which includes an enable pin not present in the SOT-23 version. The non-discharge designation distinguishes it from the AP7354D variants.

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

Does the AP7354-45W5-7 include an output discharge feature?

No, the AP7354-45W5-7 does not include an output discharge feature. The AP7354D-45W5-7 variant is available if output discharge functionality is required.

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

The EN pin serves as the chip enable control. Driving the pin high turns the regulator on, while pulling it low places the device into shutdown mode. It must not be left floating.
