NCV8768

Ultra Low Iq 150 mA LDO

Regulator with Window

Watchdog, Enable and

Reset

The NCV8768 is 150 mA LDO regulator with integrated window

watchdog and reset functions dedicated for microprocessor

applications. Its robustness allows NCV8768 to be used in severe

automotive environments. Ultra low quiescent current as low as 31

mA

typical makes it suitable for applications permanently connected to

battery requiring ultra low quiescent current with or without load. The

Enable function can be used for further decrease of quiescent current

down to 1

mA.

The NCV8768 contains protection functions as current limit and

thermal shutdown.

Features

• Output Voltage Options: 5 V

• Output Voltage Accuracy: $1.5% (TJ = 25°C to 125°C)

• Output Current up to 150 mA

• Ultra Low Quiescent Current: Typ 31 mA (max 35 mA)

• Very Low Dropout Voltage

• Enable Function

• Microprocessor Compatible Control Functions:

♦ Reset with Adjustable Power−on Delay

♦ Window Watchdog

• Wide Input Voltage Operation Range: up to 40 V

• Protection Features:

♦ Current Limitation

♦ Reverse Output Current

♦ Thermal Shutdown

• These are Pb−Free Devices

Typical Applications

• Body Control Module

• Instruments and Clusters
