The AZ1117H-5.0 is a low dropout (LDO) voltage regulator manufactured by BCD Semiconductor Manufacturing Limited. Designed to provide a stable 5.0V output, even when the input voltage is close to the output, this regulator is well-suited for battery-powered applications and systems with varying input voltages. Due to its 'END-OF-LIFE' status, it is crucial to check availability and consider alternative parts 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: 5.0V
• 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 5.0V 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-5.0 is typically available in a SOT-223 package, designed for surface mounting. It requires external capacitors for stable operation; refer to the datasheet for specific recommended values and types. The regulator operates within a defined temperature range. Given that this part is designated 'END-OF-LIFE,' it is essential to verify stock availability with BCD Semiconductor Manufacturing Limited or their distributors. Also, evaluate potential replacement components for future projects. Always refer to the datasheet for complete specifications and application guidelines.
