The AIC1117CM is a low dropout (LDO) linear regulator manufactured by Analog Integrations Corporation. This regulator is designed to provide a stable and accurate output voltage from a wide range of input voltages. It's commonly used in battery-powered devices, post-regulation for switching regulators, and other applications where a clean and stable power supply is essential.

Applications

• Battery-powered devices
• Post-regulation for switching regulators
• Microprocessor power supplies
• Linear power supplies
• Portable electronics

Features

• Low dropout voltage
• Fixed and adjustable output voltage options
• Over-current protection
• Thermal shutdown protection
• High accuracy output voltage

Benefits

• Efficient power conversion, especially in battery-powered applications, due to low dropout voltage, which maximizes battery life.
• Protection against damage from excessive current draw with over-current protection.
• Prevention of thermal damage under fault conditions due to thermal shutdown protection.
• Stable and reliable power supply for sensitive electronic components due to the high accuracy output voltage.

Additional Details

The AIC1117CM typically has a dropout voltage of around 1.2V at the rated current. It is available in both fixed voltage versions (e.g., 3.3V, 5V) and an adjustable version that can be programmed using external resistors. The device's output voltage accuracy is typically within ±1%. Its operating temperature range is generally from -40°C to +125°C. It often comes in a SOT-223 package. Specific electrical characteristics, such as the maximum input voltage and output current, should be verified from the manufacturer's datasheet to ensure suitability for the intended application. The SOT-223 package is designed for good thermal dissipation.
