The AZ1117-2.5TRE1 is a low dropout (LDO) linear regulator manufactured by BCD Semiconductor Manufacturing Limited. It provides a fixed 2.5V output voltage and is designed for applications requiring a stable and regulated voltage supply from a higher input voltage, even when the input voltage is close to the output voltage.

Applications

• Post regulators for switching power supplies
• Battery-powered systems
• Microcontroller power supplies
• Portable electronics
• Linear regulation in various electronic circuits

Features

• Fixed 2.5V output voltage: Provides a stable and precise output voltage.
• Low dropout voltage: Operates with a small difference between input and output voltage.
• Overcurrent protection: Protects the regulator from damage due to excessive output current.
• Thermal shutdown protection: Protects the regulator from overheating.
• High ripple rejection: Filters out noise and ripple from the input voltage.

Benefits

• Stable voltage supply: Ensures reliable operation of sensitive electronic components.
• Extended battery life: Low dropout voltage allows for efficient use of battery power.
• Protection against damage: Overcurrent and thermal shutdown protection prevent damage to the regulator and connected components.
• Clean output voltage: High ripple rejection ensures a clean and stable output voltage.
