The LT1086CT-3.3 is a high-performance linear LDO (Low Dropout Regulator) that offers a stable output voltage of 3.3V with a maximum current output of 1.5A. This 3-pin, TO-220 package regulator is designed for point-of-load applications where high efficiency and low noise are critical.
The LT1086CT-3.3 features a very low dropout voltage of 250mV at 1A, ensuring minimal power loss even when the input voltage is close to the output voltage. Its high efficiency, combined with a typical quiescent current of 25 A at no load, allows for reduced heat dissipation and longer battery life in portable devices.
The regulator also provides excellent load transient response with a fast slew rate of 20V/ s, enabling it to quickly adjust output voltage to meet the changing load requirements. Its high input voltage range of 2.3V to 36V makes it suitable for use in a wide range of power sources, from single-cell batteries to multi-cell power supplies.
The LT1086CT-3.3 is equipped with a precision internal reference and hysteresis-based output voltage control to maintain output voltage stability over temperature and load changes. Its low noise, typically 10mV peak-to-peak, makes it ideal for applications requiring low noise, such as audio amplifiers, DACs, and ADCs.
The regulator provides excellent thermal management with thermal shutdown protection, which turns off the output when the junction temperature exceeds 150 C, preventing damage to the device. It also offers over-current protection, which shuts down the output when the output current exceeds the maximum rated current, ensuring safe operation in overload conditions.
In summary, the LT1086CT-3.3 is a versatile and high-performance linear LDO regulator that delivers stable output voltage, high efficiency, and low noise in a compact TO-220 package. Its wide input voltage range, fast slew rate, and excellent thermal and over-current protection make it a reliable choice for point-of-load applications.
