MAX6033BAUT25#TG16

Overview

The MAX6033BAUT25#TG16 is a high-precision series voltage reference with a fixed 2.5V output, ±0.2% initial accuracy, and a maximum temperature coefficient of 15ppm/°C over the automotive range (-40°C to +125°C). It operates on a 2.7V to 12.6V supply, draws 40µA quiescent current, and sources up to 15mA. The device features low dropout voltage (max 200mV), low noise (16µVP-P at 0.1Hz to 10Hz), and excellent load regulation (0.001mV/mA typical). Packaged in a miniature SOT-23-6, it utilizes bandgap technology with laser-trimmed thin-film resistors for stability.
