19-1613; Rev 3; 3/02 Low-Cost, Micropower, Low-Dropout, High-Output-Current, SOT23 Voltage References Features The MAX6100–MAX6107 are low-cost, low-dropout (LDO), micropower voltage references. These three-terminal references are available with output voltage options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. They feature a proprietary curvature-correction circuit and laser-trimmed, thin-film resistors that result in a low temperature coefficient of 75ppm/°C (max) and an initial accuracy of ±0.4% (max). These devices are specified over the extended temperature range (-40°C to +85°C). ♦ Ultra-Small 3-Pin SOT23 Package These series-mode voltage references draw only 90µA of supply current and can source 5mA and sink 2mA of load current. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, these devices offer a supply current that is virtually independent of the supply voltage (with only a 4µA/V variation with supply voltage) and do not require an external resistor. Additionally, these internally compensated devices do not require an external compensation capacitor and are stable with load capacitance. Eliminating the external compensation capacitor saves valuable board area in space-critical applications. Lowdropout voltage and supply independent, ultra-low supply current make these devices ideal for battery-operated, high-performance, low-voltage systems. ♦ Low 75ppm/°C Temperature Coefficient The MAX6100–MAX6107 are available in tiny 3-pin SOT23 packages.

Locate the capacitor as close to IN as possible. Where transient performance is less important, no capacitor is necessary. Output/Load Capacitance Devices in the MAX6100 family do not require an output capacitance for frequency stability. They are stable for any capacitive load when sourcing less than 200µA. When sourcing greater than 200µA, the output may become unstable with capacitive loads between 0.5nF and 50nF. In applications where the load or the supply can experience step changes, an output capacitor reduces the amount of overshoot (undershoot) and improves the circuit’s transient response. Many applications do not require an external capacitor, and the MAX6100 family can offer a significant advantage in these applications when board space is critical. 1s/div Supply Current The quiescent supply current of the series-mode MAX6100 family is typically 90µA and is virtually independent of the supply voltage, with only an 8µA/V (max) variation with supply voltage. Unlike series references, shunt-mode references operate with a series resistor connected to the power supply. The quiescent current of a shunt-mode reference is thus a function of the input voltage. Additionally, shunt-mode references have to be biased at the maximum-expected load current, even if the load current is not present at the time. In the MAX6100 family, the load current is drawn from the input voltage only when required, so supply current is not wasted and efficiency is maximized at all input voltages. This improved efficiency reduces power dissipation and extends battery life. When the supply voltage is below the minimum specified input voltage (as during turn-on), the devices can draw up to 400µA beyond the nominal supply current. The input voltage source must be capable of providing this current to ensure reliable turn-on. Output Voltage Hysteresis Output voltage hysteresis is the change of output voltage at TA = +25°C 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. ______________________________________________________________________________________ 13 MAX6100–MAX6107 Typical Operating Characteristics (continued) (TA = +25°C, unless otherwise noted.) Turn-On Time These devices typically turn on and settle to within 0.1% of their final value in 50µs to 300µs. The turn-on time can increase up to 1.5ms with the device operating at the minimum dropout voltage and the maximum load.
