General Description

The MAX6100–MAX6107 are low-cost, low-dropout

(LDO), micropower voltage references. These three-ter-

minal references 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 low

temperature coefficient of 75ppm/°C (max) and an initial

accuracy of ±0.4% (max). These devices are specified

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

These series-mode voltage references draw only 90µA of

supply current and can source 5mA and 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 (with only a

4µA/V variation with supply voltage) and do not require

an external resistor. Additionally, these internally compen-

sated devices do not require an external compensation

capacitor and are stable with load capacitance.

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 MAX6100–MAX6107 are available in tiny 3-pin

SOT23 packages.
