NCV8668

NCV8668 LDO Regulator - Very Low Iq, Window Watchdog, Enable and Reset 150 mA The NCV8668 is 150 mA LDO regulator with integrated window watchdog and reset functions dedicated for microprocessor applications. Its robustness allows NCV8668 to be used in severe automotive environments. Very low quiescent current as low as 38 mA typical makes it suitable for applications permanently connected to battery requiring very low quiescent current with or without load. The Enable function can be used for further decrease of quiescent current down to 1 mA. The NCV8668 contains protection functions as current limit and thermal shutdown. 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 150 mA Very Low Quiescent Current: Typ 38 mA (max 43 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 Occupant Protection and Comfort Powertrain VBAT V in V out Cin 0.1 mF NCV8668 Vout Cout 2.2 mF OFF ON RO WDI EN WM1 WM2 GND VDD Microprocessor RESET I/O I/O I/O Figure 1.
