Description
The MAX6133 high-precision, low-power, low-dropout voltage reference features a low 3ppm/°C (max) temperature coefficient and a low dropout voltage (200mV, max). This series-mode device features bandgap technology for low-noise performance and excellent accuracy. Load regulation specifications are guaranteed for source currents up to 15mA. The laser-trimmed, high-stability thin-film resistors, together with post-package trimming, guarantee an excellent initial accuracy specification (0.04%, max). The MAX6133 is a series voltage reference and consumes only 40µA of supply current (virtually independent of supply voltage). Series-mode references save system power and use minimal external components compared to 2-terminal shunt references.

The MAX6133 is available in 8-pin µMAX and SO packages. The unique blend of tiny packaging and excellent precision performance make these parts ideally suited for portable and communication applications.
