LT3060EDC Description

The LT3060EDC from Analog Devices Inc. is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in demanding applications. With an adjustable output range of 0.6V to 44.5V and a maximum input voltage of 45V, it delivers a stable 100mA output current with exceptional accuracy. The device features a remarkably low dropout voltage of 0.51V at 100mA, ensuring efficient operation even with minimal headroom. Its ultra-low quiescent current of 80 µA and excellent power supply rejection ratio (PSRR) of 85dB at 120Hz make it ideal for noise-sensitive circuits. Packaged in an 8-pin DFN surface-mount form factor, the LT3060EDC is optimized for compact designs.
