The LT1965EMS8E-3.3#PBF is a low-dropout linear voltage regulator (LDO) from Analog Devices. It has a wide input voltage range, varying from 2.5 V to 18 V. It provides a regulated output voltage up to 3.3V, delivering current up to 1.1A. The regulator features fast transient response, ultra-low noise, and excellent load/line regulation while consuming only a small amount of quiescent current. Housed in an 8-lead MSOP package, this LDO operates over a junction temperature range of -40°C to +125°C. It is suitable for a variety of low power voltage regulation applications, such as powering microcontrollers, RF transceivers, and media processors.
