General Description

The MAX6061–MAX6068 are precision, low-dropout,

micropower voltage references. These three-terminal

devices are available with output voltage options of

1.25V, 1.8V, 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 ±0.2% (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.
