General Description
The MAX6101–MAX6105 are low-cost, low-dropout
(LDO), micropower voltage references. These three-termi-
nal references operate with an input voltage range from
(VOUT + 200mV) to 12.6V and are available with output
voltage options of 1.25V, 2.5V, 3V, 4.096V, and 5V. They
feature a proprietary curvature-correction circuit and
laser-trimmed thin-film resistors that result in a low tem-
perature 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 compensat-
ed devices do not require an external compensation
capacitor and are stable with up to 1µF of load capaci-
tance. Eliminating the external compensation capacitor
saves valuable board area in space-critical applications.
Their LDO voltage and supply-independent, ultra-low
supply current make these devices ideal for battery-oper-
ated, high-performance, low-voltage systems.
The MAX6101–MAX6105 are available in tiny 3-pin
SOT23 packages.

Note 1: Devices are 100% production tested at TA = +25°C and are guaranteed by design from TA = TMIN to TMAX by correlation to
sample units characterized over temperature.
Note 2: Temperature coefficient is specified by the “box” method; i.e., the maximum VOUT is divided by the maximum t.
Note 3: Not production tested. Guaranteed by design.
Note 4: Thermal hysteresis is defined as the change in +25°C output voltage before and after temperature cycling of the device
from TA = TMIN to TMAX.
Note 5: Dropout voltage is the minimum input voltage at which VOUT changes 0.2% from VOUT at VIN = 5.0V (VIN = 5.5V for
MAX6105).
