The MAX6061-MAX6068 are precision, low-dropout, micropower voltage references. These three-terminal devices provide 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V output voltage options. 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 resis- tor. 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 sup- ply current make these devices ideal for battery-operat- ed, high-performance, low-voltage systems. The MAX6061-MAX6068 are available in a 3-pin SOT23 package.
The MAX6061–MAX6068 family provides precision, low‑dropout voltage references in an ultra‑small 3‑pin SOT23 package. They are designed for battery‑operated, high‑performance, low‑voltage systems and support a wide range of output voltages (1.25 V, 1.8 V, 2.048 V, 2.5 V, 3 V, 4.096 V, 4.5 V, 5 V). Typical applications include ADCs, portable devices, notebooks, PDAs, GPS units, DMMs, and cellular phones.
Key specifications include a very low quiescent supply current of about 90 µA, source current up to 5 mA, sink current up to 2 mA, a maximum dropout voltage of 200 mV at 1 mA load, and a temperature coefficient of 20 ppm/°C (max). The devices operate from 2.5 V to 12.6 V supply voltage and are rated for –40 °C to +85 °C operating temperature.
