LT1963AES8-1.8 Low-Dropout Linear Regulator

The LT1963AES8-1.8 is a high-performance, low-dropout linear regulator (LDO) from Linear Technology, designed to deliver a continuous output current of up to 1.5A with a dropout voltage of just 340mV at full load. This makes it an excellent choice for applications requiring a low voltage supply with a minimal difference between the input and output voltages.

Key Features

• Output Voltage: The device provides a fixed output voltage of 1.8V, which is ideal for powering sensitive analog and digital circuits that require a precise and stable voltage supply.
• High Current Capability: With the ability to deliver up to 1.5A of output current, this LDO can comfortably power a wide range of components, from microprocessors to RF devices.
• Low Dropout Voltage: The low dropout voltage of only 340mV at full load ensures efficient operation, even when the input voltage is very close to the output voltage, thereby extending battery life in portable applications.
• Low Noise: The LT1963AES8-1.8 is optimized for low noise operation, making it suitable for noise-sensitive applications like audio and RF systems.
• Stable with Low ESR Capacitors: The regulator is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than other types of capacitors. This allows for the use of smaller, cheaper, and more reliable capacitors while maintaining stability.
• Thermal Protection: The device includes internal thermal shutdown protection to safeguard the regulator and your application from overheating and potential damage.
• Adjustable Output: While the LT1963AES8-1.8 is a fixed voltage version, other versions in the family offer an adjustable output voltage for a more flexible power supply design.
