XC6223T171GR-G

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

The XC6223T171GR-G is a high-speed LDO voltage regulator from Torex Semiconductor, featuring built-in inrush current protection and an output current capacity of 300mA. It provides a fixed 1.7V output with ±1% accuracy for voltages at or above 2.0V, though this specific part operates within the lower range where precision is maintained via laser trimming. The device supports an input voltage range of 1.6V to 5.5V and offers low power consumption with a typical supply current of 100μA. It includes comprehensive protection circuits such as current limiting, short-circuit protection, thermal shutdown, and inrush current prevention. The component utilizes a USP-4 surface-mount package and ensures stable operation with low ESR ceramic capacitors.

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

Verify the exact ordering suffix GR-G confirms the USP-4 package format and reel quantity specifications. Ensure the design accounts for the specific thermal dissipation requirements associated with the USP-4 footprint under maximum load conditions. Confirm that the selected input and output capacitors meet the low ESR criteria mandated for phase compensation stability. Cross-reference the manufacturing date code against current RoHS compliance declarations to ensure environmental standard adherence.

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

Select this variant when a fixed 1.7V rail is required with integrated inrush protection. The USP-4 package suits space-constrained PCB layouts compared to larger alternatives. Consider the thermal performance limits if operating near the upper bounds of the input voltage range. Verify compatibility with low ESR ceramic capacitors for optimal transient response and loop stability during dynamic load changes.

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

This component belongs to the XC6223 series of high-speed LDO regulators designed for portable electronic applications. The series emphasizes low noise, high accuracy, and compact packaging solutions. The 'T' designation indicates the inclusion of inrush current protection and CE pull-down features, while the '171' specifies the 1.7V output voltage setting. The 'GR-G' suffix denotes the USP-4 package type with halogen-free and lead-free compliant materials.

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

Direct substitutes include other XC6223 variants with identical electrical characteristics but different output voltages or package types, such as XC6223x181GR-G for 1.8V output. Ensure any replacement maintains the USP-4 footprint and pinout configuration to facilitate drop-in installation without PCB redesign.
