General Description

The MAX6133 high-precision, low-power, low-dropout

voltage reference features a low 3ppm/°C (max) temper-

ature coefficient and a low dropout voltage (200mV,

max). This series-mode device features bandgap tech-

nology for low-noise performance and excellent accura-

cy. 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 specifi-

cation (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 pack-

ages. The unique blend of tiny packaging and excellent

precision performance make these parts ideally suited

for portable and communication applications.
