LT3080EQ

LT3080EQ Description

The LT3080EQ from Analog Devices Inc. is a high-performance, adjustable linear voltage regulator designed for precision power management in demanding applications. With an input voltage range up to 36V and an output current capability of 1.1A, it provides a highly stable and flexible power solution. The regulator features a single-resistor output voltage adjustment, enabling 0V to 36V output range, making it ideal for low-dropout (LDO) applications where tight regulation is critical. Its low quiescent current (10.1 µA) and high PSRR (75dB at 120Hz) ensure efficiency and noise immunity, while soft-start control minimizes inrush current.
