The MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/
MAX6045/MAX6050 precision bandgap references use
a proprietary curvature-correction circuit and laser-
trimmed thin-film resistors, resulting in a low tempera-
ture coefficient of <20ppm/°C and initial accuracy of
better than 0.2%. These devices can sink and source
up to 500µA with <200mV of dropout voltage, making
them attractive for use in low-voltage applications.
Devices in this family do not require an output capaci-
tance for frequency stability. They are stable for capac-
itive loads from 0 to 2.2nF. However, in applications
where the load or the supply can experience step
changes, an output capacitor will reduce the amount of
overshoot (or undershoot) and assist the circuit’s tran-
sient response. Many applications do not need an
external capacitor, and this family can offer a signifi-
cant advantage in these applications when board
space is critical.

The quiescent supply current of these series-mode ref-
erences is a maximum of 35µA and is virtually indepen-
dent of the supply voltage, with only a 0.8µA/V variation
with supply voltage. Unlike series references, shunt-
mode references operate with a series resistor con-
nected to the power supply. The quiescent current of a
shunt-mode reference is thus a function of the input
voltage. Additionally, shunt-mode references have to
be biased at the maximum expected load current, even
if the load current is not present all the time. The load
current is drawn from the input voltage only when
required, so supply current is not wasted and efficiency
is maximized at all input voltages. This improved effi-
ciency can help reduce power dissipation and extend
battery life.
When the supply voltage is below the minimum speci-
fied input voltage (as during turn-on), the devices can
draw up to 200µA beyond the nominal supply current.
The input voltage source must be capable of providing
this current to ensure reliable turn-on.
Output voltage hysteresis is the change in the output
voltage at T
cycled over its entire operating temperature range.
Hysteresis is caused by differential package stress
appearing across the bandgap core transistors. The
typical temperature hysteresis value is 130ppm.
