High-Output-Current, SOT23 Voltage References

General Description Features

The MAX6100–MAX6107 are low-cost, low-dropout Ultra-Small 3-Pin SOT23 Package (LDO), micropower voltage references. These three-ter-

Low Cost

minal references are available with output voltage options

of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. No Output Capacitor Required

They feature a proprietary curvature-correction circuit

Stable with Capacitive Loads

and laser-trimmed, thin-film resistors that result in a low

temperature coefficient of 75ppm/°C (max) and an initial Load Regulation (2m A Sink): 8m V/m A (max) accuracy of ±0.4% (max). These devices are specified Load Regulation (5m A Source): 0.9m V/m A (max)

over the extended temperature range (-40°C to +85°C).

±0.4% (max) Initial Accuracy

These series-mode voltage references draw only 90µA of

Low 75ppm/°C Temperature Coefficient

supply current and can source 5m A and sink 2m A of load

current. Unlike conventional shunt-mode (two-terminal) 125µA (max) Quiescent Supply Current

references that waste supply current and require an

external resistor, these devices offer a supply current that is virtually independent of the supply voltage (with only a 4µA/V variation with supply voltage) and do not require an external resistor. Additionally, these internally compen- Ordering Information sated devices do not require an external compensation
