MAX6001MAX6005 13-1395 Rev 1 4/99 Low-Cost, Low-Power, Low-Dropout, SOT23-3 Voltage References General Description Features The MAX6001MAX6005 family of SOT23, low-cost 1% max Initial Accuracy series voltage references meets the cost advantage of 100ppm/C max Temperature Coefficient shunt references and offers the power-saving advantage of series references, which traditionally cost more. Unlike 45A max Quiescent Supply Current conventional shunt-mode (two-terminal) references that 0.8A/V Supply Current Variation with V IN must be biased at the load current and require an exter- nal resistor, these devices eliminate the need for an 400A Output Source and Sink Current external resistor and offer a supply current that is virtually 100mV Dropout at 400A Load Current independent of the supply voltage. These micropower, low-dropout, low-cost devices are 0.12V/A Load Regulation ideal for high-volume, cost-sensitive 3V and 5V battery- 8V/V Line Regulation operated systems with wide variations in supply voltage that require very low power dissipation. Additionally, Stable with C = 0 to 2.2nF LOAD these devices are internally compensated and do not require an external compensation capacitor, saving valuable board area in space-critical applications.
