3ppm/°C, Low-Power, Low-Dropout Voltage Reference
General DescriptionThe 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.
