XC6209F52ADR-G

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

The XC6209F52ADR-G is a positive voltage Low Dropout (LDO) regulator manufactured by Torex Semiconductor using CMOS processes. It provides a fixed output voltage of 5.2V with ±2% accuracy. The device supports a maximum output current of 300mA and features an active-high Control Enable (CE) pin without an internal pull-down resistor. Key electrical specifications include a typical dropout voltage of 180mV at 100mA, a supply current of 25μA, and a standby current of 0.01μA. It operates within an input voltage range of 2V to 10V and maintains stability with low ESR ceramic capacitors.

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

Verify the specific package type and marking code against the official datasheet before procurement. Confirm that the CE pin logic matches the system design, as this variant lacks an internal pull-down resistor. Ensure input and output capacitor selections comply with the low ESR requirements specified in the application notes to maintain stability.

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

Select this component for applications requiring a fixed 5.2V rail with high ripple rejection. The Type F designation indicates an active-high CE control without a pull-down resistor; ensure the driving signal actively pulls the pin low during shutdown. Consider thermal dissipation limits based on the USP-6B package and ambient operating temperature range.

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

This part belongs to the XC6209 series of high-speed LDO regulators from Torex Semiconductor. The series is characterized by low noise, high precision, and compatibility with small ceramic capacitors. The 'F' suffix denotes a 300mA output capability with active-high enable logic, while the 'DR-G' suffix specifies the USP-6B surface-mount package and RoHS compliance.

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

What is the logic state required to disable the output?

For the Type F regulator, the CE pin is active-high. To disable the output and enter standby mode, the CE pin must be pulled to the VSS (Ground) level.

Does this device have an internal pull-down resistor on the CE pin?

No, the XC6209F series does not have an internal pull-down resistor. An external circuit must actively drive the CE pin low to ensure the device shuts down reliably.
