The APL1086-3.3UC-TR is a low dropout (LDO) linear regulator manufactured by Anpec Electronics. It is designed to provide a stable and regulated 3.3V output voltage from a higher input voltage. LDO regulators are known for their ability to operate with a small voltage difference between the input and output, making them well-suited for battery-powered and other low-voltage applications.

Applications

• Motherboards: Used for voltage regulation to power sensitive components.
• Graphics Cards: Provides a stable power supply for graphics processing units (GPUs) and memory.
• LCD Monitors: Employed in the power supply section to generate the required voltages.
• Set-Top Boxes: Used to regulate voltage for integrated circuits and other components.
• Embedded Systems: Provides regulated power for microcontrollers and other digital circuits.

Features

• Low Dropout Voltage: Enables operation with a minimal difference between input and output voltage.
• 3.3V Fixed Output Voltage: Provides a stable and regulated output voltage.
• High Output Current: Capable of delivering up to 1.5A of output current.
• Over-Current Protection: Protects the regulator from damage due to excessive current draw.
• Over-Temperature Protection: Protects the regulator from thermal damage.
• Adjustable Output Voltage (with external components): Allows for output voltage adjustment using external resistors (depending on the specific variant).

Benefits

• Stable Power Supply: Ensures stable and regulated output voltage, enhancing the reliability of connected components.
• High Efficiency: Minimizes power dissipation and optimizes battery life in portable applications.
• Protection Features: Protects the regulator and connected components from potential damage.
• Compact Size: Enables compact designs.

Additional Details

The APL1086-3.3UC-TR is typically available in a TO-263 package. Key specifications include a dropout voltage of 1.3V at 1.5A, a line regulation of 0.015% (typical), and a load regulation of 0.05% (typical). It requires external capacitors for stability. It is designed to operate over a wide temperature range. The LDO regulator also includes a thermal shutdown feature which activates when the junction temperature exceeds a certain limit. UC in the part number generally indicates the package type, and TR signifies tape and reel packaging.
