NCV4949A: Linear Voltage Regulator, LDO, 100 mA, with Reset and Sense

Description: The NCV4949A is a monolithic integrated 5.0 V volt...
  • The NCV4949A is a monolithic integrated 5.0 V voltage regulator with a very low dropout and additional functions such as reset and an uncommitted voltage sense comparator. It is designed for supplying microcontroller/microprocessor controlled systems particularly in automotive applications. The NCV4949A has improved reset behavior for lower input and output voltage levels.
  • Features
  • Very Low Dropout Voltage Less Than 0.4V - Operates at lower input voltage during cranking.
  • Integrated Voltage Sense Comparator and Power On Reset - Decrease BOM cost and save space while managing microcontroller power management
  • Programmable Reset Pulse Delay With External Capacitor - Design flexibility
  • Integrated Protections:
    - Thermal Shutdown
    - Short Circuit
    Transient Input Voltage Up to 40V - Suitable in harsh automotive environment
  • 5.0V / 100mA High Precision Standby Output Voltage +/- 1% at 25C ambient temperature
  • AEC-Q100 qualified
