V TEMP ( at T J = T 0 )
Temp Output
The MAX6173–MAX6177 provide a temperature output
proportional to die temperature. TEMP can be calculated
from the following formula:
TEMP (V) = T J (°K) x n
where T J = the die temperature,
n = the temperature multiplier,
n = ? 1 . 9 mV / ° K
T 0
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 MAX6173 –MAX6177 do not require an output
capacitor for stability and are stable with capacitive
loads up to 100μF. In applications where the load or the
10,000
1000
100
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 MAX6173–MAX6177 consume 320μA (typ) of qui-
escent supply current. This improved efficiency
reduces power dissipation and extends battery life.
Thermal Hysteresis
Thermal hysteresis is the change in the output voltage
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 MAX6173–MAX6177 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 MAX6173–MAX6177 feature a short-circuit-protected
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 circuiting
the output to the input.
