NCV8141
5.0 V, 500 mA Linear
Regulator with ENABLE,
RESET
, and Watchdog
The NCV8141 is a linear regulator suited for microprocessor
applications in automotive environments.
This ON Semiconductor part provides 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.
The NCV8141 provides a low sleep mode current as compared to
the CS8141. Consult your local sales representative for a low sleep
mode current version of the CS8140.

PIN FUNCTION DESCRIPTION
Pin Symbol Function
1 V
IN
Supply voltage to IC, usually direct from the battery.
2 ENABLE CMOS compatible logical input. V
OUT
is disabled when ENABLE is LOW and WDI is invalid.
3 RESET CMOS compatible output lead. RESET goes low whenever V
OUT
drops 4.5% below its typical value for
more than 2.0 ms or WDI signal falls below the watchdog threshold frequency.
4 GND Ground Connection.
5 Delay Timing capacitor for Watchdog and RESET functions.
6 WDI CMOS compatible input lead. The Watchdog function monitors the falling edge of the incoming digital
pulse train. The signal is usually generated by the system microprocessor.
7 V
OUT
Regulated output voltage, 5.0 V (typ).
