XC6209F21ADR-G

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

The XC6209F21ADR-G is a high-speed, low-noise positive voltage LDO regulator manufactured by Torex Semiconductor using CMOS processes. It features an active-high CE control with no internal pull-down resistor and delivers up to 300mA output current depending on the specific output voltage setting. The device offers highly accurate output voltages in 0.05V increments ranging from 0.9V to 6.0V, with ±2% accuracy for outputs above 1.5V. It operates within a 2.0V to 10V input range and includes built-in phase compensation, allowing compatibility with low ESR ceramic capacitors for stable performance under load fluctuations.

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

Verify the specific ordering suffix DR-G corresponds to the USP-6B package format as indicated in the product classification table. Confirm that the 'F' type designation aligns with the required 300mA maximum output current capability for your target application voltage. Ensure the CE pin logic matches the system design, as this variant lacks an internal pull-down resistor, requiring external biasing or connection to VIN/VSS to prevent unstable operation.

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

Select this component when a higher current capacity than the standard 150mA types is required. The F-type designation indicates an Active High control logic without a built-in pull-down resistor, necessitating careful CE pin interfacing. Verify that the desired output voltage falls within the 0.9V to 6.0V range available in 0.05V increments. Consider the thermal dissipation limits of the USP-6B package relative to the expected load current and ambient temperature conditions.

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 and high ripple rejection. The XC6209F variant specifically provides increased current drive capabilities compared to the A-D types, making it suitable for applications demanding higher transient response and load handling while maintaining low dropout characteristics.

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

Direct substitutes include other XC6209 types with matching current ratings and control logic, such as XC6209E series (Active High with pull-down) if the external circuit can accommodate the different CE pin behavior. Cross-reference package dimensions for USP-6B equivalents from other manufacturers if supply constraints exist, ensuring electrical parameters like dropout voltage and PSRR remain compatible.
