VT222AFCR-ADJ

Overview

The VT222AFCR-ADJ is a precision, low-dropout (LDO) voltage regulator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an adjustable output voltage range, allowing for flexible system design configurations. The device incorporates internal compensation and protection mechanisms to ensure stable operation under varying load conditions. Key electrical characteristics include a specified input voltage range, output current capability, and dropout voltage performance typical of high-precision LDO regulators in this series.

Feature Summary

• Adjustable output voltage configuration for customized power supply requirements
• Low dropout operation enabling efficient power conversion from higher input voltages
• Integrated thermal shutdown and current limiting for enhanced reliability

Applications

• Portable battery-powered equipment requiring precise voltage regulation
• Industrial control systems needing stable analog supply rails
• Communication infrastructure modules with strict noise sensitivity

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm pinout compatibility and package type. Ensure the ordering information matches the required tolerance and temperature grade. Cross-reference the manufacturer's latest documentation to avoid obsolete revisions. Confirm availability through authorized distributors only to prevent counterfeit components.

Selection Notes

Select this component when an adjustable output voltage is required within the specified input range. Consider the thermal dissipation capabilities based on the expected load current and ambient temperature. Evaluate the quiescent current impact on overall system efficiency. Ensure the package style fits the available PCB real estate and manufacturing constraints.

Part Context

This part belongs to the VT222 family of low-dropout linear regulators designed for high-performance applications. The 'ADJ' suffix indicates an adjustable output version, distinct from fixed-voltage variants. It is part of Analog Devices' portfolio aimed at providing reliable power management solutions for demanding electronic environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family that offer fixed voltages if adjustment is unnecessary. Verify equivalent electrical specifications such as dropout voltage and load transient response before substituting with parts from other manufacturers.
