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

Verify the specific ordering suffix '15' confirms the 1.5V fixed output voltage. Confirm the 'FGE' suffix matches the required U-DFN3030-8 (Type E) package dimensions. Ensure the '-7' suffix aligns with the specified tape and reel packaging quantity of 3000 units per reel. Cross-reference the datasheet revision against the manufacturing date code on received components.

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

Select this component when a stable 1.5V rail is required with minimal voltage drop across the regulator. The integrated power-good feature simplifies system startup sequencing compared to standard LDOs. Verify that the application's maximum ambient temperature and power dissipation requirements fit within the U-DFN3030-8 thermal limits to prevent triggering the internal thermal shutdown circuitry.

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

What is the purpose of the PG pin?

The PG pin is an open-drain output that indicates when the output voltage has reached the regulation threshold. It goes high-impedance when VOUT exceeds the rising threshold and pulls low if VOUT drops below the falling threshold or if the device is disabled.

How does the short circuit protection work?

When the output is shorted to ground, the device triggers fold-back short circuit protection, clamping the output current to approximately 400mA. Full current capability is restored once the output voltage recovers above 15% of its nominal value.
