The AME1117ACBTZ is a low dropout (LDO) linear regulator manufactured by AME, Inc. This regulator is designed to provide a stable and regulated voltage output from an input voltage that can be only slightly higher than the desired output voltage. This makes it suitable for applications where efficiency is crucial and the voltage difference between the input and output is minimal.

Applications

• Post Regulation for Switching Power Supplies: Used to clean up and stabilize the output voltage of switching power supplies.
• Battery Powered Systems: Ideal for regulating voltage in battery-powered devices, ensuring consistent performance as the battery discharges.
• Linear Regulator for Microcontrollers: Provides a stable voltage source for microcontrollers and other digital circuits.
• Power Management in Portable Devices: Used in devices like smartphones, tablets, and wearable electronics to manage power efficiently.

Features

• Low Dropout Voltage: Operates with a very small difference between input and output voltage, improving efficiency.
• Fixed Output Voltage: Provides a stable and precise fixed output voltage.
• Over Current Protection: Protects the regulator and connected circuitry from damage due to excessive current draw.
• Thermal Overload Protection: Shuts down the regulator if the internal temperature exceeds a safe limit, preventing damage.
• High Accuracy: Ensures a precise and stable output voltage under varying load conditions.

Benefits

• Improved Efficiency: Reduces power loss due to its low dropout voltage, extending battery life in portable devices.
• Reliable Performance: Provides a stable and regulated voltage, ensuring consistent performance of connected devices.
• Protection Against Damage: Over current and thermal overload protection mechanisms prevent damage to the regulator and connected circuitry.
• Simplified Design: Requires minimal external components, simplifying circuit design and reducing overall system cost.

The AME1117ACBTZ is typically available in a SOT-223 package. Its specifications include a low dropout voltage typically around 1V at full load, and an output voltage accuracy of ±1%. The regulator also features a quiescent current of typically 5mA. It is designed to operate over a wide temperature range, making it suitable for various environmental conditions.
