The MAX873/MAX875/MAX876 provide a temperature
output proportional to die temperature. TEMP can be cal-
culated from the following formula:
where T
n = the temperature multiplier,
T
Self-heating affects the die temperature and conversely,
the TEMP output. The TEMP equation assumes the output
is not loaded. If device power dissipation is negligible,
then T
For the best line-transient performance, decouple the
input with a 0.1µF ceramic capacitor as shown in the
Typical Operating Circuit . Place the capacitor as close
to IN as possible. When transient performance is less
important, no capacitor is necessary.
The MAX873/MAX875/MAX876 do not require an output
capacitor for stability and are stable with capacitive
loads up to 100µF. In applications where the load or the

supply can experience step changes, a larger output
capacitor reduces the amount of overshoot (under-
shoot) and improves the circuit’s transient response.
Place output capacitors as close to the devices as pos-
sible for best performance.
The MAX873/MAX875/MAX876 consume 320µA (typ) of
quiescent supply current. This improved efficiency
reduces power dissipation and extends battery life.
Thermal hysteresis is the change in the output voltage
at T
over its entire operating temperature range. Hysteresis
is caused by differential package stress appearing
across the bandgap core transistors. The typical ther-
mal hysteresis value is 120ppm.
The MAX873/MAX875/MAX876 typically turn on and settle
to within 0.1% of the preset output voltage in 150µs
(2.5V output). The turn-on time can increase up to
150µs with the device operating with a 1µF load.
The MAX873/MAX875/MAX876 feature a short-circuit-pro-
tected output. Internal circuitry limits the output current
to 60mA when short circuiting the output to ground.
The output current is limited to 3mA when short circuit-
ing the output to the input.
