MAX6133 19-2266 Rev 2 6/03 3ppm/C, Low-Power, Low-Dropout Voltage Reference General Description Features The MAX6133 high-precision, low-power, low-dropout Low Temperature Coefficient voltage reference features a low 3ppm/C (max) temper- 3ppm/C (max), SO ature coefficient and a low dropout voltage (200mV, 5ppm/C (max), MAX max). This series-mode device features bandgap tech- Tiny 5mm 3mm MAX Package nology for low-noise performance and excellent accura- cy. Load regulation specifications are guaranteed for Low 200mV (max) Dropout Voltage source currents up to 15mA. The laser-trimmed, high- Low 40A Quiescent Current stability thin-film resistors, together with post-package trimming, guarantee an excellent initial accuracy specifi- 0.04% (max) Initial Accuracy cation (0.04%, max). The MAX6133 is a series voltage Low 16V Noise (0.1Hz to 10Hz) (2.5V Output) reference and consumes only 40A of supply current P-P (virtually independent of supply voltage). Series-mode 15mA Output Source-Current Capability references save system power and use minimal external components compared to 2-terminal shunt references. Wide 2.7V to 12.6V Supply Voltage The MAX6133 is available in 8-pin MAX and SO pack- Excellent Line (30V/V, max) and ages. The unique blend of tiny packaging and excellent Load (0.05mV/mA, max) Regulation precision performance make these parts ideally suited for portable and communication applications.
