19-1659; Rev 1; 4/01 Precision, Micropower, Low-Dropout, High-Output-Current, SOT23 Voltage References General Description Features MAX6061–MAX6068 The MAX6061–MAX6068 are precision, low-dropout, o Ultra-Small 3-Pin SOT23 Package micropower voltage references. These three-terminal o devices are available with output voltage options of ±0.2% (max) Initial Accuracy 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. o 20ppm/°C (max) Temperature Coefficient They feature a proprietary curvature-correction circuit o and laser-trimmed thin-film resistors that result in a very 5mA Source Current low temperature coefficient of 20ppm/°C (max) and an o 2mA Sink Current initial accuracy of ±0.2% (max). Specifications apply to o No Output Capacitor Required the extended temperature range (-40°C to +85°C). o The MAX6061–MAX6068 typically draw only 90μA of Stable with Capacitive Loads supply current and can source 5mA or sink 2mA of load o 90μA (typ) Quiescent Supply Current current. Unlike conventional shunt-mode (two-terminal) o 200mV (max) Dropout at 1mA Load Current references that waste supply current and require an external resistor, these devices offer a supply current o Output Voltage Options: 1.25V, 1.8V, 2.048V, 2.5V, that is virtually independent of the supply voltage 3V, 4.096V, 4.5V, 5V (8μA/V variation) and do not require an external resis- o 13μVp-p Noise 0.1Hz to 10Hz (MAX6061) tor. Additionally, the internally compensated devices do not require an external compensation capacitor. Eliminating the external compensation capacitor saves Ordering Info
