NCV8772

Ultra Low Iq 350 mA LDO

Regulator with Enable and

Reset

The NCV8772 is 350 mA LDO regulator with integrated reset

functions dedicated for microprocessor applications. Its robustness allows

NCV8772 to be used in severe automotive environments. Ultra low

quiescent current as low as 24

mA typical makes it suitable for

applications permanently connected to battery requiring ultra low

quiescent current with or without load. This feature is especially critical

when modules remain in active mode when ignition is off. The Enable

function can be used for further decrease of quiescent current in

shutdown mode to 1

mA. The NCV8772 contains protection functions as

current limit, thermal shutdown and reverse output current protection.

Features

• Output Voltage Options: 3.3 V and 5 V

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

• Output Current up to 350 mA

• Ultra Low Quiescent Current: typ 24 mA (max 30 mA)

• Very Wide Range of Cout and ESR Values for Stability

• Enable Function

− 1

mA Max Quiescent Current when disabled

• Microprocessor Compatible Control Functions:

− Reset with Adjustable Power−On Delay

• Wide Input Voltage Operation Range: up to 40 V

• Protection Features

− Current Limitation

− Thermal Shutdown

− Reverse Output Current Protection

• These are Pb−Free Devices

Typical Applications

• Body Control Module

• Instruments and Clusters

• Occupant Protection and Comfort

• Powertrain
