13-1395; Rev 1; 4/99 Low-Cost, Low-Power, Low-Dropout, SOT23-3 Voltage References Features The MAX6001-MAX6005 family of SOT23, low-cost series voltage references meets the cost advantage of shunt references and offers the power-saving advantage of series references, which traditionally cost more. Unlike conventional shunt-mode (two-terminal) references that must be biased at the load current and require an external resistor, these devices eliminate the need for an external resistor and offer a supply current that is virtually independent of the supply voltage. 1% max Initial Accuracy These micropower, low-dropout, low-cost devices are ideal for high-volume, cost-sensitive 3V and 5V batteryoperated systems with wide variations in supply voltage that require very low power dissipation. Additionally, these devices are internally compensated and do not require an external compensation capacitor, saving valuable board area in space-critical applications. 0.12V/A Load Regulation 100ppm/C max Temperature Coefficient 45A max Quiescent Supply Current 0.8A/V Supply Current Variation with VIN 400A Output Source and Sink Current 100mV Dropout at 400A Load Current 8V/V Line Regulation Stable with CLOAD = 0 to 2.2nF Applications Ordering Information Portable/Battery-Powered Equipment Notebook Computers TEMP.

(Note 6) MAX6001-MAX6005 Low-Cost, Low-Power, Low-Dropout, SOT23-3 Voltage References Pin Description PIN NAME 1 IN FUNCTION Supply Voltage Input 2 OUT Reference Voltage Output 3 GND Ground Detailed Description The MAX6001-MAX6005 bandgap references offer a temperature coefficient of <100ppm/C and initial accuracy of better than 1%. These devices can sink and source up to 400A with <200mV of dropout voltage, making them attractive for use in low-voltage applications. Supply Current The quiescent supply current of these series-mode references is a maximum of 45A and is virtually independent of the supply voltage, with only a 0.8A/V variation with supply voltage. Unlike shunt-mode references, the load current of these series-mode references is drawn from the supply voltage only when required, so supply current is not wasted and efficiency is maximized over the entire supply voltage range. This improved efficiency can help reduce power dissipation and extend battery life. When the supply voltage is below the minimum specified input voltage (as during turn-on), the devices can draw up to 200A beyond the nominal supply current. The input voltage source must be capable of providing this current to ensure reliable turn-on. Applications Information Output Voltage Hysteresis Output/Load Capacitance Output voltage hysteresis is the change in the output voltage at TA = +25C before and after the device is cycled over its entire operating temperature range. Hysteresis is caused by differential package stress appearing across the bandgap core transistors. The typical temperature hysteresis value is 130ppm. Devices in this family do not require an output capacitance for frequency stability. They are stable for capacitive loads from 0 to 2.2nF. However, in applications where the load or the supply can experience step changes, an output capacitor will reduce the amount of overshoot (or undershoot) and assist the circuit's transient response. Many applications do not need an external capacitor, and this family can offer a significant advantage in these applications when board space is critical.
