Technology The BCT1117ELT33-TR is a Low Dropout Regulator (LDO) from BroadChip Technology that is manufactured in a SOT-223-3 RoHS package. It is designed for use in a variety of applications, including voltage regulation, noise reduction, signal conditioning, power factor correction, and impedance matching. Features of this LDO include low voltage operation, high current capacity, and low output noise, as well as a temperature-compensated reference arm that provides a constant output voltage even in the presence of heat or load changes. In addition, its high power supply rejection ratio and tight output voltage regulation reduce power dissipation and make it ideal for efficient power management in applications such as automotive, industrial, and consumer electronics.
