LT3060IDC

LT3060IDC Description

The LT3060IDC 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 while maintaining exceptional efficiency. The device features a remarkably low dropout voltage of 0.51V at 100mA and a quiescent current of just 80µA, making it ideal for power-sensitive designs. Its 85dB PSRR (120Hz) ensures superior noise rejection, critical for analog and RF circuits. Packaged in an 8-pin DFN surface-mount format, the LT3060IDC is optimized for compact, high-reliability systems, though it is now marked as obsolete.
