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

Verify the specific ordering suffix '12' confirms the fixed 1.2V output configuration. Confirm the package code 'FGE' matches the required U-DFN3030-8 (Type E) footprint. Ensure the reel quantity '7' aligns with manufacturing requirements. Cross-reference the datasheet revision DS41964 Rev. 2 - 2 for accurate electrical parameters.

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

Select this component when a fixed 1.2V rail is required with integrated power-good signaling. The inclusion of the PG pin distinguishes it from standard AP7361 variants lacking this feature. Verify that the system's maximum ambient temperature and power dissipation constraints fit within the U-DFN3030-8 thermal limits.

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

This part belongs to the AP7361E series, which adds a Power-Good function compared to the base AP7361 family. It utilizes the U-DFN3030-8 (Type E) package, offering a compact surface-mount solution. The series is designed for low-to-medium power applications requiring precise voltage regulation and efficient standby modes.

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

What is the function of the PG pin on the AP7361E?

The PG pin is an open-drain output that indicates when the output voltage has reached its regulated level. It goes into a high-impedance state when VOUT exceeds the threshold and pulls low if VOUT drops below the threshold or the device is disabled.

How does the AP7361E handle short circuits?

The device features fold-back short circuit protection that clamps the output current to approximately 400mA when the output is shorted to ground. Full current is restored once the output voltage recovers above 15% of its nominal value.
