APPLICATION INFORMATION
Auto-Discharge Function
MAS9124 has a shutdown transistor that turns on,
when the device is disabled, and discharges the
output capacitor.
Calculating Maximum Power Dissipation
Maximum power dissipation of the package may
limit output current or input voltage, which can be
used, especially with the combination of low output
voltage and high input voltage.
The power dissipation can be calculated by using
the formula:

It shall not exceed the maximum power dissipation,
allowed by the package:

where TJMAX is maximum junction temperature
(TJMAX = 125°C), TA is ambient temperature and RJA
is junction-to-ambient thermal resistance of the
package.
When assumed that:
TA = +55°C, VOUT = 1.5 V, VIN = 5.0 V and used
package is SOT23-5 the equation yields:

VIN * IGND is negligible and can be omitted.
Consequently, it can be seen that under these
conditions the average output current should not
exceed 105 mA.
