The AZ1085S-5.0E1 is a low dropout (LDO) voltage regulator manufactured by BCD Semiconductor Manufacturing Limited. It's designed to maintain a stable 5.0V output even with a small difference between input and output voltages. This is particularly useful in battery-powered devices. The 'END-OF-LIFE' status means verifying availability and considering alternatives for new designs is crucial.

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 1.3V at 3A output current.
• Fixed Output Voltage: 5.0V
• High Accuracy: Output voltage tolerance of ±2%.
• Current Limiting: Protects against overcurrent situations.
• Thermal Shutdown: Prevents the regulator from overheating.
• Available in surface mount packages for efficient assembly.

Benefits

• Extends battery life in portable devices because of the low dropout characteristic.
• Provides a consistent and accurate 5.0V supply for electronic components.
• Safeguards the regulator and connected circuits from overcurrents and overheating.
• Simplifies design due to the fixed output voltage option.
• Compact size saves board space.

Additional Details

The AZ1085S-5.0E1 typically comes in a TO-263 package suitable for surface mounting on PCBs. It requires external capacitors for stability; the datasheet specifies the values and types. It is designed to operate within a specific temperature range. Since it's marked as 'END-OF-LIFE,' check with BCD Semiconductor or distributors for stock and possible replacements for new applications. Always refer to the datasheet for comprehensive specifications and application advice.
