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.
The MAX6133 is a series‑mode voltage reference offering high precision, low temperature coefficient (3 ppm/°C max) and low dropout voltage (200 mV max). It operates from 2.7 V to 12.6 V supply and provides up to 15 mA output source current while consuming only 40 µA quiescent current.
Typical applications include precision regulators, A/D and D/A converters, power supplies, high‑accuracy industrial control, and hand‑held instruments. The device is available in 8‑pin µMAX and SO packages and requires a minimum 0.1 µF output capacitor for stability.
