Temp Output
The MAX873/MAX875/MAX876 provide a temperature
output proportional to die temperature. TEMP can be cal-
culated from the following formula:
TEMP (V) = T J (°K) x n
where T J = the die temperature,
n = the temperature multiplier,
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.
Supply Current
The MAX873/MAX875/MAX876 consume 320μA (typ) of
quiescent supply current. This improved efficiency

reduces power dissipation and extends battery life.
Thermal Hysteresis
Thermal hysteresis is the change in the output voltage
T A = the ambient temperature.
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 J ≈ T A .
Applications Information
Bypassing/Output Capacitance
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

at T A = +25 ° C before and after the device is cycled
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.
Turn-On Time
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.
Short-Circuited Outputs
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.
