These three-terminal devices 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 very low temperature coefficient of 20ppm/°C (max) and an initial accuracy of ±0.2% (max). Specifications apply to the extended temperature range (-40°C to +85°C). The MAX6061–MAX6068 typically draw only 90µA of supply current and can source 5mA or 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 (8µA/V variation) and do not require an external resistor. Additionally, the internally compensated devices do not require an external compensation capacitor. Eliminating the external compensation capacitor saves valuable board area in space-critical applications. Low dropout voltage and supply independent, ultra-low supply current make these devices ideal for battery-operated, high-performance, low-voltage systems. The MAX6061–MAX6068 are available in a 3-pin SOT23 package.

Temperature Coefficient is measured by the “box” method, i.e., the maximum ∆VOUT is divided by the maximum ∆T. Temperature Hysteresis is defined as the change in +25°C output voltage before and after cycling the device from TMIN to TMAX. Dropout voltage is the minimum input voltage at which VOUT changes ≤ 0.2% from VOUT at VIN = 5.0V (VIN = 5.5V for MAX6065). _______________________________________________________________________________________ 9 MAX6061–MAX6068 ELECTRICAL CHARACTERISTICS—MAX6065, VOUT = 5.000V Typical Operating Characteristics (VIN = +5V for MAX6061–MAX6068, VIN = +5.5V for MAX6065, IOUT = 0, TA = +25°C, unless otherwise noted.)

The extremes of these characteristics are found in the MAX6061 (1.25V output) and the MAX6065 (5.0V output). The Typical Operating Characteristics of the remainder of the MAX6061 family, typically lie between these two extremes and can be estimated based on their output voltages. 14 ______________________________________________________________________________________ Precision, Micropower, Low-Dropout, High-Output-Current, SOT23 Voltage References PIN NAME 1 IN 2 OUT Reference Output 3 GND Ground Typical Operating Circuit FUNCTION +SUPPLY INPUT (SEE SELECTOR GUIDE) Input Voltage IN OUT REFERENCE OUT MAX6061MAX6068 * Applications Information Input Bypassing For the best line-transient performance, decouple the input with a 0.1µF ceramic capacitor as shown in the Typical Operating Circuit. 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 MAX6061 family do not require an output capacitance for frequency stability. In applications where the load or the supply can experience step changes, an output capacitor of at least 0.1µF will reduce the amount of overshoot (undershoot) and improve the circuit’s transient response. Many applications do not require an external capacitor, and the MAX6061 family can offer a significant advantage in these applications when board space is critical. Supply Current The quiescent supply current of the series-mode MAX6061 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 MAX6061 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. GND 1µF * *CAPACITORS ARE OPTIONAL. Ordering Information (continued) PART TEMP.

Hysteresis is caused by differential package stress appearing across the bandgap core transistors. The typical temperature hysteresis value is 130ppm. Turn-On Time These devices typically turn on and settle to within 0.1% of their final value in 50µs to 300µs, depending on the device. The turn-on time can increase up to 1.5ms with the device operating at the minimum dropout voltage and the maximum load.
