Precision, Micropower, Low-Dropout, High-Output-Current, SOT23 Voltage References
General Description
The MAX6061-MAX6067 are precision, low-dropout, micropower voltage references. These three-terminal devices operate with an input voltage range from (VOUT + 50mV typ) to 12.6V and are available with output voltage options of 1.25V, 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 0.02% (max). Specifications apply to the extended temperature range (-40C to +85C). The MAX6061-MAX6067 typically draw only 90A 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 (8A/V variation) and do not require an external resistor. Additionally, the internally compensated devices do not require an external compensation capacitor and are stable with up to 1F of load capacitance. 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-MAX6067 are available in a 3-pin SOT23 package. o Ultra-Small 3-Pin SOT23 Package o 0.2% max Initial Accuracy o 20ppm/C max Temperature Coefficient o 5mA Source Current at 0.5mV/mA o 2mA Sink Current at 1.3mV/mA o Stable with CLOAD = 0 to 1F o 90A typ Quiescent Supply Current o 200mV max Dropout at 1mA Load Current o +10V/V Line Regulation o Output Voltage Options: 1.25V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, 5V o 13Vp-p Noise 0.1Hz to 10Hz (MAX6061)

All devices are 100% production tested at TA = +25C and are guaranteed by design for TA = TMIN to TMAX, as specified. 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 +25C output voltage before and after cycling the device from TMIN to TMAX. Not production tested. Guaranteed by design. Dropout voltage is the minimum input voltage at which VOUT changes 0.2% from VOUT at VIN = 5.0V (VIN = 5.5V for MAX6065).

Note 6: Many of the MAX6061 family Typical Operating Characteristics are extremely similar. 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 voltage.

Supply Current
The quiescent supply current of the series-mode MAX6061 family is typically 90A and is virtually independent of the supply voltage, with only an 8A/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 400A beyond the nominal supply current. The input voltage source must be capable of providing this current to ensure reliable turn-on.
Applications Information
Input Bypassing
For the best line-transient performance, decouple the input with a 0.1F 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. They are stable for capacitive loads from 0 to 1F. However, in applications where the load or the supply can experience step changes, an output capacitor 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.
Output Voltage Hysteresis
Output voltage hysteresis is the change of 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.

Figure 1 shows a typical method for developing a bipolar reference. The circuit uses a MAX681 voltage doubler/inverter charge-pump converter to power an ICL7652, thus creating a positive as well as a negative reference voltage.

Turn-On Time
These devices typically turn on and settle to within 0.1% of their final value in 50s to 300s, 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.
