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

Verify the specific ordering suffixes to confirm the package type and environmental compliance status. Ensure the CE pin is connected to either VIN or VSS to prevent undefined operational states. Confirm that the required output voltage falls within the selectable range and matches the laser-trimmed specification for the designated part number.

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

Select this regulator for applications requiring stable regulation from high input voltages up to 28V. The inclusion of the CE function makes it suitable for battery-powered systems where standby current reduction is critical. Verify that the thermal dissipation requirements are met by the PCB layout, as the device relies on board heat sinking for higher power loads.

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

What happens if the CE pin is left open?

Leaving the CE pin open results in an undefined operation state. For the XC6701B series, the IC may become unstable; it must be connected to either VIN or VSS to ensure normal operation.

How does the thermal shutdown function operate?

When the junction temperature reaches approximately 150°C, the thermal protection circuit activates and turns off the driver transistor. Operation automatically resumes when the temperature drops to the release level.
