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

Verify the specific ordering suffix W5 corresponds to the SOT-25 package configuration required for your design. Confirm that the D suffix indicates the inclusion of the active output discharge feature, which distinguishes it from standard versions. Ensure compatibility with RoHS3 and halogen-free manufacturing standards if applicable to your supply chain requirements.

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

Select this component when a stable 4.5V rail is needed from a single-cell lithium or similar power source. The SOT-25 package offers a balance of thermal performance and board space efficiency compared to larger packages. Consider the 0.35V dropout voltage to ensure sufficient headroom between input and output voltages under maximum load conditions.

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

This part belongs to the AP7354 series of 150mA ultra-low quiescent current LDOs. The 'D' suffix denotes the version with output discharge capability, while 'W5' specifies the SOT-25 surface-mount package.

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

What is the function of the EN pin on the AP7354D-45W5-7?

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.

How does the AP7354D differ from the standard AP7354?

The AP7354D includes an active output discharge feature that pulls the output voltage down quickly when the device is disabled, whereas the standard AP7354 does not have this function.
