CS8122
2.0% 5.0 V, 750 mA Low
Dropout Linear Regulator
with Delayed RESET
The CS8122 is a precision 5.0 V linear regulator capable of sourcing
in excess of 750 mA. The RESET’s delay time is externally
programmed using a discrete RC network. During power up, or when
the output goes out of regulation, the RESET lead remains in the low
state for the duration of the delay. This function is independent of the
input voltage and will function correctly as long as the output voltage
remains at or above 1.0 V. Hysteresis is included in the Delay and the
RESET 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.
The regulator is protected against a variety of fault conditions: i.e.
reverse battery, overvoltage, short circuit and thermal runaway
conditions. The regulator is protected against voltage transients ranging
from −50 V to +40 V. Short circuit current is limited to 1.2 A (typ).
The CS8122 is an improved replacement for the CS8126 and
features a tighter tolerance on its output voltage (2.0% vs. 4.0%).
The CS8122 is packaged in a 5 lead TO−220 with copper tab. The
copper tab can be connected to a heat sink if necessary.
