MAX6133

19-2266; Rev 2; 6/03 www.DataSheet4U.com 3ppm/°C, Low-Power, Low-Dropout Voltage Reference General 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, highstability 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. o Low Temperature Coefficient 3ppm/°C (max), SO 5ppm/°C (max), µMAX o Tiny 5mm ✕ 3mm µMAX Package o Low 200mV (max) Dropout Voltage o Low 40µA Quiescent Current o ±0.04% (max) Initial Accuracy o Low 16µVP-P Noise (0.1Hz to 10Hz) (2.5V Output) o 15mA Output Source-Current Capability o Wide 2.7V to 12.6V Supply Voltage o Excellent Line (30µV/V, max) and Load (0.05mV/mA, max) Regulation Features MAX6133 Applications Precision Regulato...
