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

Verify the specific ordering suffix PR-G corresponds to the SOT-89-5 package configuration before procurement. Confirm that the active high logic level without internal pull-down resistors aligns with the system's control interface requirements to prevent unstable operation when the CE pin is left open. Ensure compliance with EU RoHS and halogen-free standards indicated by the -G suffix.

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

What is the logic state for enabling the output on the XC6209B192PR-G?

The XC6209B type features an Active High CE pin logic. The output is enabled when the CE pin voltage is at a High Level and disabled when at a Low Level.

Does the XC6209B192PR-G have internal pull-down resistors on the CE pin?

No, the Type B designation indicates that there is no pull-down resistor built into the CE pin. External circuitry must define the pin state to prevent instability.
