NCV8774
Ultra Low Iq 350 mA LDO
Regulator
The NCV8774 is a 350 mA LDO regulator. Its robustness allows
NCV8774 to be used in severe automotive environments. Ultra low
quiescent current as low as 18 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 NCV8774
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 18 mA (max 23 mA)
• Very Wide Range of Cout and ESR Values for Stability
• Wide Input Voltage Operation Range: up to 40 V
• Protection Features
− Current Limitation
− Thermal Shutdown
• These are Pb−Free Devices
Typical Applications
• Body Control Module
• Instruments and Clusters
• Occupant Protection and Comfort
• Powertrain
