The LT3045IMSE#PBF is a high-performance linear regulator from Analog Devices, featuring an ultralow noise and ultrahigh PSRR architecture suitable for noise-sensitive applications. It provides an output current of 500mA with a typical dropout voltage of 260mV. The device operates over a wide input voltage range of 1.8V to 20V and offers an output voltage range from 0V to 15V.
Key electrical characteristics include ultralow RMS noise of 0.8µVRMS (10Hz to 100kHz), ultralow spot noise of 2nV/√Hz at 10kHz, and ultrahigh PSRR of 76dB at 1MHz. It also features a high bandwidth of 1MHz and a precision 100µA SET pin current with ±1% initial accuracy. The regulator is stable with a minimum 10µF ceramic output capacitor.
Built-in protection features include reverse-battery protection, reverse-current protection, internal current limit with foldback, and thermal limit with hysteresis. The LT3045 is available in thermally enhanced 12-lead MSOP and 10-lead 3mm x 3mm DFN packages, supporting surface mount applications.
This regulator is ideal for applications such as RF power supplies, very low noise instrumentation, high-speed/high-precision data converters, and precision power supplies. Its parallelable design allows for reduced noise and increased output current.
