Low-Cost, Low-Power, Low-Dropout,
SOT23-3 Voltage References
The MAX6001–MAX6005 bandgap references offer a
temperature coefficient of <100ppm/°C and initial accura-
cy of better than 1%. These devices can sink and source
up to 400µA 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 45µA and is virtually indepen-
dent of the supply voltage, with only a 0.8µA/V variation
with supply voltage. Unlike shunt-mode references, the
load current of these series-mode references is drawn
from the supply voltage only when required, so supply
current is not wasted and efficiency is maximized over
the entire supply voltage range. This improved efficien-
cy can help reduce power dissipation and extend bat-
tery 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.
