The APL1087-18DC-TRL is a low dropout (LDO) linear regulator manufactured by Anpec Electronics. This LDO is designed to provide a stable 1.8V output voltage with a low dropout voltage, making it suitable for applications where the input voltage is close to the output voltage. This is especially useful in battery-powered or low-voltage systems.

Applications

• Portable Devices: Commonly used in smartphones, tablets, and other battery-powered devices.
• Microcontroller Power: Provides stable power to microcontrollers in embedded systems.
• Memory Power: Used to supply power to memory chips in various devices.
• FPGA Power: Used in Field-Programmable Gate Arrays (FPGAs) to regulate core and I/O voltages.
• Consumer Electronics: Found in a variety of consumer electronics devices such as digital cameras and MP3 players.

Features

• Low Dropout Voltage: Operates efficiently with a small difference between input and output voltages.
• 1.8V Fixed Output Voltage: Provides a stable and accurate 1.8V output.
• High Output Current: Capable of delivering a specified output current (consult datasheet for the exact value).
• Over-Current Protection: Protects the regulator from damage due to excessive current.
• Thermal Shutdown Protection: Shuts down the regulator if the temperature exceeds safe limits.
• Enable Pin: Allows the regulator to be turned on or off for power saving.

Benefits

• Stable Output: Provides a stable and regulated 1.8V output, ensuring reliable operation of connected components.
• High Efficiency: Minimizes power loss and improves battery life in portable devices.
• Protection Features: Protects the regulator and connected devices from potential damage.

Additional Details

The APL1087-18DC-TRL is typically available in a SOT-223 package. Key specifications include a dropout voltage that is typically less than 0.5V at the rated output current (consult datasheet). It requires external capacitors for stable operation. It is designed to operate over a specified temperature range. Specific parameters to consider include dropout voltage at rated current, quiescent current, and thermal resistance. 'DC' and 'TRL' suffixes likely refer to the specific package type and tape and reel packaging, respectively.
