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

Verify the specific ordering suffix DR-G confirms the USP-6B surface-mount package and Halogen-free compliance. Ensure the A-series designation matches the required active-high enable logic with an internal pull-down resistor. Confirm the 31 code corresponds to the exact 3.1V output voltage specification before finalizing procurement orders.

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

Select this part when a fixed 3.1V rail is required with up to 700mA load capability. The A-series type is suitable for systems requiring an active-high enable signal with a default shutdown state due to the internal pull-down resistor. Verify that the application utilizes low ESR ceramic output capacitors to maintain stability without external phase compensation components.

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

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

What is the function of the CE pin on the XC6210A31ADR-G?

The CE pin controls the ON/OFF status of the regulator. For the A-series, it is active-high; applying a high level activates the output, while a low level or open circuit places the device in standby mode.

Does the XC6210A31ADR-G require external feedback resistors?

No, the output voltage is internally fixed at 3.1V. External resistors are not needed for voltage setting, though input and output capacitors are required for stability.
