Top Searches for this datasheet19-4777; 4/01 Precision, Low-Power, Low-Dropout, SOT23-3 Voltage References MAX6045/MAX6050 precision, low-dropout, micropower voltage references available miniature SOT23-3 surface-mount packages. They feature proprietary curvature-correction circuit laser-trimmed thin-film resistors that result temperature coefficient <15ppm/°C initial accuracy better than 0.2%. These devices specified over extended temperature range. These series-mode voltage references draw only 27µA quiescent supply current sink source 500µA load current. Unlike conventional shuntmode (two-terminal) references that waste supply current require external resistor, devices MAX6012 family offer supply current that's virtually independent supply voltage (with only 0.8µA/V variation with supply voltage) require external resistor. Additionally, these internally compensated devices require external compensation capacitor stable with 2.2nF load capacitance. Eliminating external compensation capacitor saves valuable board area space-critical applications. Their dropout voltage supply-independent, ultra-low supply current make these devices ideal battery-operated, low-voltage systems. 0.2% (max) Initial Accuracy 15ppm/°C (max) Temperature Coefficient 35µA (max) Quiescent Supply Current 0.8µA/V Supply Current Variation with ±500µA Output Source Sink Current 100mV Dropout 500µA Load Current 0.12µV/µA Load Regulation 8µV/V Line Regulation Stable with CLOAD 2.2nF Features Ordering Information PART TEMP.

Precision, Low-Power, Low-Dropout, SOT23-3 Voltage References Description NAME FUNCTION Supply Voltage Input Reference Voltage Output Ground Supply Current quiescent supply current these series-mode references maximum 35µA virtually independent supply voltage, with only 0.8µA/V variation with supply voltage. Unlike series references, shuntmode references operate with series resistor connected power supply. quiescent current shunt-mode reference thus function input voltage. Additionally, shunt-mode references have biased maximum expected load current, even load current present time. load current drawn from input voltage only when required, supply current wasted efficiency maximized input voltages. This improved efficiency help reduce power dissipation extend battery life. When supply voltage below minimum specified input voltage during turn-on), devices draw 200µA beyond nominal supply current. input voltage source must capable providing this current ensure reliable turn-on.
