The AZ1085S-5.0 is a low dropout (LDO) voltage regulator produced by BCD Semiconductor Manufacturing Limited. It is designed to provide a stable 5.0V output voltage with a minimal voltage difference between the input and output, making it ideal for battery-powered and other applications where input voltage may vary. Due to its 'END-OF-LIFE' status, designers should verify its 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 1.3V at 3A output current.
• Fixed Output Voltage: 5.0V
