CS8140/D
CS8140, CS8141
5.0 V, 500 mA Linear
Regulator with ENABLE,
RESET
, and Watchdog
The CS8140 and CS8141 are linear regulators suited for
microprocessor applications in automotive environments.
These ON Semiconductor parts provide the power for the
microprocessors along with many of the control functions needed in
today’s computer based systems. Incorporating all of these features
saves both cost, and board space.
Packages are available for surface mounting as well as through hole
mounting.
The CS8141 has the same feature set as the CS8140 with the
exception of the response to the watchdog signals (WDI). The CS8141
only responds to input signals (WDI) which are below the preset
watchdog frequency threshold.
Features
