The LT1763IDE-1.8#PBF is a Low Dropout linear regulator from Analog Devices, designed to provide a stable output voltage in a more efficient and cost-effective manner than other linear regulators. It has low noise, low output voltage accuracy, and a maximum output current of 500mA. The IC has a wide range of input voltage range, from 2.5 V to 18 V, and a very low dropout voltage, typically 200 mV at the full 500 mA load. The compact SO-8 package and low profile make it great for space-constrained applications. It provides both fixed output voltages (1.8 V, 2.5 V, 2.85 V, 3.3 V, 5.0 V) and adjustable output voltages (2.5 V to 5.5 V). The device also includes features such as power-on reset and thermal protection. With its low noise, high efficiency, and compact package, the LT1763IDE-1.8#PBF is a great choice for a wide variety of applications.
