MAX6033 High-Precision, Low-Dropout SOT23 Series Voltage Reference General Description Features The MAX6033 ultra-high-precision series voltage refer- Tiny 6-Pin SOT23 Package ence features a low 7ppm/C (max) temperature coeffi- Ultra-Low Temperature Drift: 7ppm/C (max) cient and a low dropout voltage (200mV, max). Low temperature drift and low noise make the MAX6033 0.04% Initial Accuracy ideal for use with high-resolution ADCs or DACs. Stable with Capacitive Loads This device uses bandgap technology for low-noise per- Low 16V Noise (0.1Hz to 10Hz) (2.5V Output) P-P formance and excellent accuracy. Laser-trimmed, high- stability, thin-film resistors, and postpackage trimming 15mA Output Source Current guarantee excellent initial accuracy (0.04%, max). The Low 200mV Dropout Voltage MAX6033 consumes only 40A of supply current and Low 40A Quiescent Current sources up to 15mA. Series mode references save sys- tem power and use minimal external components com- Wide 2.7V to 12.6V Supply Voltage pared to two-terminal shunt references. Excellent Load Regulation: 0.001mV/mA The MAX6033 is available in the miniature 6-pin SOT23 package and is offered over the automotive tempera- Pin Configuration ture range (-40C to +125C).
