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

Verify the specific package type SOT-89-5 and the CE pin configuration for High Active logic with pull-down resistor. Confirm compliance with EU RoHS standards and Halogen/Antimony-free requirements indicated by the -G suffix. Ensure input and output capacitor values meet minimum stability requirements based on the selected output voltage range.

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

Select this component when a fixed 2.6V output is required with high current capability up to 700mA. The A-type designation indicates High Active CE logic with an internal pull-down resistor, suitable for systems where the control signal defaults to active or requires specific pull-down behavior. Consider the thermal dissipation limits in the SOT-89-5 package relative to the expected voltage drop and load current.

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

This part belongs to the XC6210 series of High Current, High Speed LDO Regulators. The series offers selectable output voltages in 0.05V increments ranging from 0.80V to 5.00V. The 'A' prefix denotes High Active CE logic with a pull-down resistor, while 'PR' specifies the SOT-89-5 package format.

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

Other parts within the XC6210 series with different output voltages or package types may serve as functional substitutes if electrical parameters align. Verify CE pin logic compatibility between A, B, C, and D types before substitution.

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

What is the function of the CE pin on the XC6210A26APR-G?

The CE pin controls the operational state of the regulator. For the A-type series, a High signal activates the regulator, while a Low signal places it in stand-by mode, significantly reducing power consumption.

How does the current limiter operate in this device?

The device incorporates a fixed current limiter and a foldback circuit. When the load current reaches the limit level, the output voltage drops, causing the foldback circuit to further reduce the output current to protect the IC.

What are the minimum capacitor requirements for stability?

For an output voltage of 2.6V, which falls in the 1.80V ~ 5.00V range, a minimum output capacitor (CL) of 1.0μF is recommended. An input capacitor (CIN) of 1.0μF is also suggested for input stabilization.
