LT1965IDD#TRPBF - Low Dropout Linear Regulator from Linear Technology

The LT1965IDD#TRPBF is a high-performance low dropout linear regulator (LDO) that delivers up to 1.1A of continuous output current with a dropout voltage of only 300mV at full load. This component, manufactured by Linear Technology, is designed to provide clean, stable power for precision applications such as sensitive RF and analog circuitry, microprocessors, and microcontrollers.

One of the standout features of the LT1965 is its low noise operation, with an output noise as low as 40µV_RMS over a 10Hz to 100kHz bandwidth when using a 10nF bypass capacitor. This makes it particularly well-suited for noise-sensitive applications such as audio and RF systems. Additionally, the device offers excellent transient response, which is critical for maintaining voltage stability during rapid load changes.

The LT1965IDD#TRPBF operates with an input voltage range from 1.8V to 20V, providing designers with a versatile solution that can accommodate a wide range of supply sources. Its adjustable output voltage can be set from 1.2V to 19.5V with a single external resistor, giving engineers flexibility in customizing the output to match specific circuit requirements.

Built-in protection features include reverse battery protection, current limiting, and thermal limiting, which safeguard the device and the load under abnormal conditions. The LT1965IDD#TRPBF also features a shutdown capability that reduces the quiescent current to less than 1µA, enhancing power efficiency in battery-powered applications.

The device is offered in a low-profile (0.75mm) 8-lead DFN package with a thermal resistance that allows for efficient heat dissipation. This package is suitable for space-constrained applications while ensuring reliable thermal performance. Additionally, the LT1965IDD#TRPBF is available in a thermally enhanced 8-lead MSOP package for applications requiring a more traditional mounting solution.

In summary, the LT1965IDD#TRPBF from Linear Technology is a robust and versatile LDO that combines low noise, high output current, and excellent transient response with a wide input voltage range and adjustable output. Its comprehensive protection features and efficient packaging options make it an ideal choice for a broad array of power regulation applications.
