P-DSO-8-3, -6, -7, -8, -9
Functional Description
This device is a 5-V low-drop fixed-voltage regulator. The
P/PG-DSO-20-1,-6,-7,-9,-14,-
maximum input voltage is 45 V. It can deliver an output
current of at least 180 mA. The IC is short-circuit proof
and features temperature protection that disables the
circuit in the event of impermissibly high temperatures. The watchdog function is
disabled as a function of the load, so that a controller is not interrupted during sleep
mode by a watchdog reset.
Application Description
The IC regulates an input voltage VI in the range 5.5 V < VI < 45 V to VQ,nom = 5.0 V. In
the event of an output voltage VQ < VRT, a reset signal is generated. The wiring of the
reset switching threshold input enables the value of VRT to be reduced. The reset delay
time can be adjusted using an external capacitor. The integrated watchdog monitors the
connected active controller. If there is no rising edge at the watchdog input, the reset
