These three-terminal 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. ♦ 20ppm/°C (max) Temperature Coefficient They feature a proprietary curvature-correction circuit ♦ and laser-trimmed thin-film resistors that result in a very 5mA Source Current low temperature coefficient of 20ppm/°C (max) and an ♦ 2mA Sink Current initial accuracy of ±0.2% (max). Specifications apply to ♦ No Output Capacitor Required the extended temperature range (-40°C to +85°C). ♦ The MAX6061–MAX6068 typically draw only 90µA of Stable with Capacitive Loads supply current and can source 5mA or sink 2mA of load ♦ 90µA (typ) Quiescent Supply Current current. Unlike conventional shunt-mode (two-terminal) ♦ 200mV (max) Dropout at 1mA Load Current references that waste supply current and require an external resistor, these devices offer a supply current ♦ 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- ♦ 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 Information valuable board area in space-critical applications. Low dropout voltage and supply independent, ultra-low sup- PIN-TOPPARTTEMP. RANGE ply current make these devices ideal for battery-operat- PACKAGEMARK ed, high-performance, low-voltage systems.
