MP6402
Dual, High PSRR 500mA Linear Regulator
With Integrated Reset Circuit
The Future of Analog IC Technology
DESCRIPTION
The MP6402 is a dual-channel, high PSRR
linear regulator with reset function.
The outputs range from 0.9V and 3.3V with
±1.5% voltage accuracy at both channels
by
operating from a +2.5V to +5.5V input. OUT2
pin voltage is recommended to be higher than
OUT1 pin voltage. Short circuit protection and
thermal protection are built in to prevent
damage caused by output short circuit and
overloading, respectively.
A reset circuit is designed to
R E
monitor output
S E T
voltage of channel 2. The
becomes
active (low) when OUT2 pin voltage drops
below its threshold. To
E
ensure that a complete
R E S T
reset occurs, the
remains active for a
pre-set delay time. The delay time is
programmable by the user through changing
the external capacitor. The MP6402 is available
in SOIC8E and 3x3mm TQFN8 packages and
is specified for operation
T
J
from -40°C to
+125°C.
