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.

TO–220

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.
