XC6209F48AMR-G

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

The XC6209F48AMR-G is a high-precision, low-noise positive voltage LDO regulator manufactured using CMOS processes by Torex Semiconductor. It features an output voltage range of 0.9V to 6.0V in 0.05V increments, with a typical accuracy of ±2% for voltages above 1.5V and ±30mV for voltages at or below 1.5V. The device supports a maximum output current of 150mA and operates within an input voltage range of 2.0V to 10V. It includes an ON/OFF control function (CE pin) that allows for active-high logic operation with a built-in pull-down resistor. The regulator is compatible with low ESR ceramic capacitors and offers high ripple rejection of 70dB at 10kHz.

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

Verify the specific ordering suffix MR-G confirms the SOT-25 package type and reel quantity specifications. Ensure the 'F' designator matches the required 150mA current rating and active-high CE logic with internal pull-down resistor. Confirm the '48A' segment corresponds to the exact nominal output voltage and ±2% accuracy tier required for the application. Cross-reference the datasheet version to ensure compliance with current environmental standards such as EU RoHS and lead-free requirements.

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

Select this component when a fixed output voltage with 0.05V resolution is required alongside active-high shutdown control. The built-in pull-down resistor on the CE pin simplifies interface design by preventing unstable states when the control signal is open. Ensure the application utilizes low ESR ceramic output capacitors to leverage the integrated phase compensation circuit. Verify that the input voltage remains within the 2.0V to 10V range and that thermal dissipation limits for the SOT-25 package are respected under maximum load conditions.

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

This part belongs to the XC6209 series of highly precise, low noise, positive voltage LDO regulators. The series is designed for portable electronic devices requiring stable power supplies with minimal external components. The F-type designation indicates a 150mA maximum output current capability, distinguishing it from the higher current E-H types which support up to 300mA depending on the output voltage setting.

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

Direct substitutes include other XC6209 variants with matching output voltage and accuracy, such as XC6209B48AxxMR-G for standard active-high logic without pull-down, or XC6209E48AxxMR-G if higher current capacity is needed. Ensure any replacement maintains the same CE pin logic polarity and internal resistor configuration to avoid circuit instability.
