XC6209F462MR-G

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

The XC6209F462MR-G is a positive voltage Low Dropout (LDO) regulator manufactured by Torex Semiconductor using CMOS processes. It provides a fixed output voltage of 4.6V with a maximum output current of 300mA. The device operates within an input voltage range of 2.0V to 10V and features a dropout voltage of 250mV at 100mA load. Key electrical characteristics include a typical supply current of 25μA, standby current of 0.01μA, and power supply rejection ratio of 70dB at 10kHz. Voltage accuracy is ±2% for outputs above 1.5V. It includes built-in overcurrent protection and an ON/OFF control function via the CE pin.

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

Verify the specific package type SOT-25 and the active-high logic level of the Control Enable (CE) pin corresponding to Type F. Confirm compliance with EU RoHS standards and absence of halogen and antimony due to the -G suffix. Ensure the selected component matches the required 4.6V output voltage and 300mA current capability for the target application design.

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

Select this component when a fixed 4.6V rail is required from a 2.0V to 10V input source with moderate current demands up to 300mA. The Type F designation indicates an active-high CE pin without internal pull-down resistors, requiring external drive logic. Consider the thermal dissipation limits of the SOT-25 package under high load conditions and ensure adequate PCB layout for heat release.

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

This part belongs to the XC6209 series of high-speed LDO regulators designed for portable electronic devices. The series utilizes CMOS technology to achieve low power consumption while maintaining high precision. The XC6209F variant specifically offers 300mA output capability with standard voltage accuracy, distinguishing it from lower current types or higher precision variants within the same family.

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

Direct substitutes within the XC6209 series include other Type F packages with different output voltages, such as XC6209F452MR-G or XC6209F502MR-G, provided the voltage requirement changes. Cross-manufacturer replacements require matching the 300mA current rating, SOT-25 package, and active-high enable logic.
