The CS8122 is a precision 5V linear reg-
ulator capable of sourcing in excess of
750mA. The
externally programmed using a discrete
RC network. During power up, or when
the output goes out of regulation, the
lead remains in the low state
for the duration of the delay. This func-
tion is independent of the input voltage
and will function correctly as long as
the output voltage remains at or above
1V. Hysteresis is included in the Delay
and the
comparators to
improve noise immunity. A latching
discharge circuit is used to discharge
the delay capacitor when it is triggered
by a brief fault condition.
s delay time is
The regulator is protected against a
variety of fault conditions: i.e. reverse
battery, overvoltage, short circuit and
thermal runaway conditions. The regu-
lator is protected against voltage tran-
sients ranging from -50V to +40V. Short
circuit current is limited to 1.2A (typ).
The CS8122 is an improved replacement
for the CS8126 and features a tighter tol-
erance on its output voltage (2% vs 4%).
The CS8122 is packaged in a 5 lead
TOD220 with copper tab. The copper tab
can be connected to a heat sink if
necessary.
