LT1965IDD-3.3#PBF - Low Noise, Low Dropout Linear Regulator

The LT1965IDD-3.3#PBF is a high-performance low dropout linear regulator (LDO) brought to you by Linear Technology, now part of Analog Devices. This regulator offers a fixed output voltage of 3.3V and is designed to deliver up to 1.1A of continuous output current with a drop-out voltage of only 300mV at full load. Its low noise and low dropout voltage make it an ideal choice for precision, high-power applications that require a stable and clean power supply.

With an input voltage range from 1.8V to 20V, the LT1965IDD-3.3#PBF provides versatile solutions for various systems. This regulator features a low quiescent current of 500µA, which reduces to less than 1µA in shutdown mode, making it suitable for battery-powered and energy-efficient applications.

The LT1965IDD-3.3#PBF is designed with an internal protection circuit that includes reverse battery protection, current limiting with foldback, and thermal limiting to ensure the device's reliability and longevity. Additionally, the fast transient response of this regulator ensures stable performance for applications with rapidly changing loads.

For noise-sensitive applications, the LT1965IDD-3.3#PBF excels with its low output noise of only 40µV RMS over a 10Hz to 100kHz bandwidth. This is particularly beneficial for precision analog circuits, such as high-end audio equipment, RF applications, and sensitive instrumentation that demand a quiet power supply.

The device is housed in a 10-lead DFN package, which offers a compact footprint while allowing for adequate thermal performance. The small size and surface-mount package make it an excellent choice for space-constrained applications requiring a high-quality power solution.

In summary, the LT1965IDD-3.3#PBF from Linear Technology is a top-tier choice for designers looking for a low noise, high-performance LDO regulator. Its robust feature set ensures reliable operation in a wide range of applications, from portable devices to industrial systems.
