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

Verify the specific part number XC6701BE72PR-G against official Torex Semiconductor documentation to confirm the 16.7V output designation and SOT-89-5 packaging. Ensure that the CE pin is properly biased to either VIN or VSS during operation to prevent undefined states, as leaving it open may cause instability. Confirm compliance with RoHS standards if required for your manufacturing process.

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

Select this component when a fixed 16.7V supply is required with high input voltage tolerance up to 28V. The inclusion of the CE function makes it suitable for battery-powered applications requiring power management through software-controlled shutdown. Verify that the expected load current remains within the 150mA limit and that the thermal dissipation capabilities of the SOT-89-5 package are sufficient for the application's power loss conditions.

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

This device belongs to the XC6701 series of high-speed voltage regulators designed for automotive and portable electronics. The series utilizes a P-channel driver transistor and offers various output voltages selectable in 0.1V increments. The 'B' designator indicates a standard operating temperature range of -40°C to 85°C, while the 'E72' suffix specifies the 16.7V fixed output voltage.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Consult the official Torex XC6701 datasheet for direct pin-compatible alternatives within the same series that offer different output voltages or package types such as SOT-25 or USP-6C. Ensure any substitute maintains the 28V input rating and CE functionality if system-level shutdown control is necessary.

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 operational state. For stable operation, the CE pin must be connected to either the VIN voltage (for ON) or VSS (for OFF).

How does the IC handle short-circuit conditions?

The IC incorporates a current fold-back circuit. When the load current reaches the limit level, the output voltage drops, reducing the output current to approximately 30mA to protect the device.
