The APL1084-33GC-TR is a low dropout (LDO) voltage regulator manufactured by Anpec Electronics. It is designed to provide a stable and regulated 3.3V output voltage from a higher input voltage. The 'GC' likely refers to the package type, and 'TR' usually denotes tape and reel packaging for automated assembly.

Applications:

• Motherboards: Used to regulate voltage for sensitive components like chipsets and memory.
• Graphics cards: Provides stable power to the GPU and memory chips.
• Embedded systems: Regulates voltage for microcontrollers, sensors, and other digital circuits.
• Power supplies: Used as a post-regulator to clean up the output voltage.
• Battery-powered devices: Provides a regulated voltage from a battery source.

Features:

• Low dropout voltage: Operates with a minimal voltage difference between input and output.
• Fixed 3.3V output: Provides a precisely regulated 3.3V output voltage.
• Overcurrent protection: Protects the regulator from damage due to excessive current draw.
• Thermal shutdown: Shuts down the regulator when the temperature exceeds a safe limit.
• Short-circuit protection: Protects the regulator from damage during short-circuit conditions.

Benefits:

• Stable voltage regulation: Provides a consistent and reliable 3.3V output voltage.
• Improved system performance: Ensures that sensitive components receive clean power.
• Increased system reliability: Protects components from damage due to voltage fluctuations or overcurrent conditions.
• Simplified system design: Reduces the need for external components to regulate voltage.
• Extended battery life: Minimizes power consumption in battery-powered devices.

Additional Details:

The APL1084-33GC-TR typically supports an input voltage range of up to 12V. It can deliver a continuous output current of up to 1.5A. The regulator features a low quiescent current, minimizing power consumption when no load is present. The 'GC' package is commonly a TO-263 or similar surface-mount package. It is compliant with RoHS standards for environmental protection.
