XC6204F312PR-G

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

The XC6204F312PR-G is a positive voltage LDO regulator from Torex Semiconductor, manufactured using CMOS processes. It provides a fixed output voltage of 3.1V with ±2% accuracy and supports a maximum output current of 300mA. The device operates within an input voltage range of 2V to 10V and features a dropout voltage of 200mV at 100mA. It includes an ON-OFF control function via the CE pin, which allows for active high logic operation without a built-in pull-down resistor. The regulator offers low power consumption with a typical supply current of 70μA and standby current of 0.01μA. It is housed in a SOT-89-5 package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrates a foldback current limiter that functions as a short-circuit protection mechanism for both the output current and the output pin.
• Features an ON-OFF control (CE) function that enables the output to be turned off, significantly reducing power consumption during standby states.
• Compatible with low ESR ceramic capacitors due to built-in phase compensation, ensuring stable output even during rapid load fluctuations.

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

Verify the specific part number against official manufacturer documentation to confirm the exact output voltage, accuracy class, and package type. Ensure the ordering suffix matches the required specifications, as variations exist within the series. Cross-reference the datasheet for absolute maximum ratings and thermal dissipation limits relevant to your PCB layout before finalizing procurement.

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

Select this component when a fixed 3.1V output with 300mA capability is required in a compact SOT-89-5 package. The F-type designation indicates active high CE logic without an internal pull-down resistor, requiring external circuit consideration if the control signal is floating. Verify that the input voltage remains within the 2V to 10V range and that the load current does not exceed the thermal limits defined by the power dissipation rating.

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

This device belongs to the XC6204/XC6205 series of high-speed LDO regulators. The XC6204 series specifically covers output voltages from 1.8V to 6.0V, while the XC6205 series covers 0.9V to 1.75V. The 'F' designator identifies it as a 300mA variant with active high CE control and no internal pull-down resistor. The 'PR-G' suffix denotes the SOT-89-5 package and RoHS compliance.

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

Direct replacements must match the 300mA output current, 3.1V fixed output, and SOT-89-5 package. Other XC6204 variants with different output voltages or accuracy levels may fit electrically but require verification of the specific voltage setting. Ensure any substitute maintains the same CE pin logic polarity (Active High) and lacks an internal pull-down resistor if the original design relies on external control.
