XC6209F27AMR-G

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

The XC6209F27AMR-G is a positive voltage Low Dropout (LDO) regulator manufactured by Torex Semiconductor using CMOS processes. It provides a fixed output voltage of 2.85V with an accuracy of ±2%. The device supports a maximum output current of 300mA and operates within an input voltage range of 2.0V to 10V. Key electrical characteristics include a typical standby current of 0.01μA, a supply current of 25μA, and a ripple rejection ratio of 70dB at 10kHz. It features a dropout voltage of approximately 270mV at 100mA load and is housed in a SOT-25 package.

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

Verify the specific ordering suffix MR-G confirms the SOT-25 package and Halogen-free compliance. Ensure the CE pin logic matches the design requirements, as Type F indicates Active High control without a built-in pull-down resistor. Confirm that the application circuit includes appropriate input and output capacitors to maintain stability given the low standby current specifications.

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

Select this component when a fixed 2.85V rail is required with high precision. The Type F designation specifies Active High enable logic without internal pull-down resistors, requiring external drive or connection to VIN/VSS. Consider the 300mA current capability and low dropout performance for battery-powered applications where efficiency and transient response are critical.

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 electronics. The series utilizes CMOS technology to achieve low noise and high ripple rejection. The XC6209F variant specifically denotes a 300mA output current capability with Active High CE logic, distinguishing it from lower current types or different enable configurations within the same family.

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

Substitutes must match the 2.85V output, 300mA current rating, and SOT-25 package. Verify CE pin polarity compatibility, as Type F requires a High signal to enable. Check if alternative parts require external pull-down resistors on the enable pin to prevent unstable operation.
