The AZ1117H-2.5 is a low dropout (LDO) voltage regulator from BCD Semiconductor Manufacturing Limited. It is engineered to deliver a stable 2.5V output voltage, even when the input voltage is only slightly higher than the output. This characteristic makes it particularly useful in battery-powered devices and other applications where the input voltage may fluctuate. Given its 'END-OF-LIFE' status, it is important to verify availability and consider alternatives for new designs.

Applications

• Post Regulators for Switching Power Supply
• Voltage reference
• Battery-powered equipment
• Linear Regulator for DVD+RW
• High Efficiency Linear Regulators
• Motherboard
• Graphics card

Features

• Low Dropout Voltage: Typically 1.1V at 1A output current.
• Fixed Output Voltage: 2.5V
• High Accuracy: Output voltage tolerance of ±1%.
• Current Limiting: Provides protection against overcurrent conditions.
• Thermal Shutdown: Protects the regulator from overheating.
• Three-Terminal Adjustable or Fixed Output Voltage

Benefits

• Extends battery life in portable devices due to its low dropout voltage.
• Provides a stable and accurate 2.5V power supply for sensitive electronic components.
• Protects the regulator and downstream circuits from damage due to overcurrent or overheating.
• Simplifies design due to the fixed output voltage.
• Suitable for adjustable voltage applications.

Additional Details

The AZ1117H-2.5 typically comes in a SOT-223 package, suitable for surface mount assembly. It requires external capacitors for stability; specific values and types are listed in the datasheet. The regulator is designed to operate within a specified temperature range. Because this component is marked as 'END-OF-LIFE,' be sure to check with BCD Semiconductor Manufacturing Limited or distributors for remaining inventory and potential replacement options for future projects. Always consult the datasheet for comprehensive specifications and application recommendations.
