The AZ1085D-5.0TRE1 is a low dropout (LDO) voltage regulator manufactured by BCD Semiconductor Manufacturing Limited. As an LDO regulator, it is designed to maintain a stable 5.0V output voltage even when the input voltage is only slightly higher than the output voltage. This makes it particularly useful in battery-powered applications where the input voltage decreases as the battery discharges. Due to its 'END-OF-LIFE' status, it is crucial to verify 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 1.3V at 3A output current.
• Fixed Output Voltage: 5.0V
• High Accuracy: Output voltage tolerance of ±2%.
• Current Limiting: Provides protection against overcurrent conditions.
• Thermal Shutdown: Protects the regulator from overheating.
• Adjustable Output Voltage (using external resistors)

Benefits

• Extends battery life in portable devices due to 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 option.
• Reduces board space requirements due to its compact package.

Additional Details

The AZ1085D-5.0TRE1 is typically available in a TO-252 package, suitable for surface mounting. It requires external capacitors for stability. The datasheet specifies the recommended values and types of capacitors. The regulator is designed to operate over a wide temperature range. Because this part is designated as 'END-OF-LIFE,' consider contacting BCD Semiconductor Manufacturing Limited or distributors for remaining stock and potential replacement parts for future designs. Be aware that the parameters of LDO regulators can drift over time and temperature, so the specified tolerances represent the initial and typical performance. Always refer to the datasheet for detailed specifications and application recommendations.
