The AME8818AEET300Z is a low-dropout (LDO) linear regulator manufactured by Ametherm. This regulator is designed to provide a stable and accurate output voltage from a higher input voltage, even when the input voltage is close to the desired output voltage. It is particularly useful in battery-powered devices and other applications where a clean and consistent voltage supply is crucial.

Applications

• Battery-powered devices
• Portable electronics
• Microcontroller power supplies
• Post-regulation for switching power supplies
• Noise-sensitive circuits

Features

• Low dropout voltage
• High output accuracy
• Low quiescent current
• Over-current protection
• Over-temperature protection
• Short-circuit protection
• Stable with ceramic capacitors

Benefits

• Extends battery life by minimizing power loss due to dropout voltage.
• Ensures stable and reliable operation of connected devices with accurate voltage regulation.
• Reduces power consumption in standby mode with low quiescent current.
• Protects the regulator and connected devices from damage due to over-current, over-temperature, or short circuits.
• Simplifies circuit design and reduces component count with its ability to operate with ceramic capacitors.

Additional Details

The AME8818AEET300Z is a 3.0V fixed-output LDO regulator. Its low dropout voltage allows it to maintain regulation even when the input voltage drops very close to 3.0V. The low quiescent current minimizes power consumption when the regulator is in standby mode, which is crucial for battery-powered applications. The built-in over-current, over-temperature, and short-circuit protection features ensure robust and reliable operation in harsh environments. It's commonly used in applications where space and power efficiency are critical concerns.
