LT1963ET-3.3#PBF - Low Noise, Fast Transient Response LDO Regulator

The LT1963ET-3.3#PBF is a high-performance low dropout linear regulator (LDO) from Linear Technology, now part of Analog Devices, designed to provide a stable and clean power supply. This LDO is particularly suitable for noise-sensitive applications due to its low noise characteristics and fast transient response. It is capable of delivering up to 1.5A of continuous output current with a dropout voltage of 340mV at full load, which makes it an excellent choice for tight spaces where heat dissipation is a concern.

With an output voltage fixed at 3.3V, the LT1963ET-3.3#PBF ensures a stable voltage supply for a variety of digital and analog circuits. The device operates with an input voltage range from 3.8V to 20V, providing flexibility for use in multiple applications, from battery-powered devices to industrial equipment.

The LT1963ET-3.3#PBF features several protective functions that enhance its reliability and longevity. It includes over-current protection, which safeguards the device and the load from damage due to excessive current. Additionally, it has thermal shutdown protection that prevents overheating, ensuring the regulator operates within safe temperature limits.

Another significant advantage of this LDO regulator is its low quiescent current, which makes it an ideal choice for battery-powered applications where power efficiency is critical. The quiescent current is typically only 1mA, which helps to extend battery life.

The regulator is provided in a TO-220 package, which is known for its robustness and excellent thermal performance. The LT1963ET-3.3#PBF also features an adjustable version that allows setting the output voltage from 1.21V to 20V with the use of external resistors, providing additional versatility for specific design requirements.

In summary, the LT1963ET-3.3#PBF from Linear Technology is a top choice for engineers looking for a high-quality, reliable LDO regulator that combines low noise, fast transient response, and a fixed 3.3V output with a wide input voltage range and robust protection features.
