LT3027IDD#PBF

LT3027IDD#PBF Description

The LT3027IDD#PBF from Analog Devices Inc. is a high-performance, dual-output, low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. Housed in a compact 10-DFN package, it delivers adjustable output voltages ranging from 1.22V to 20V, with a maximum input voltage of 20V. Each of its two independent regulators provides 100mA output current, making it ideal for dual-rail systems. The device features an ultra-low dropout voltage of 0.45V at full load, ensuring efficient operation even with minimal headroom. Its 65dB PSRR (120Hz) minimizes noise, critical for sensitive analog and digital circuits.
