NCV4290: 450 mA LDO Linear Voltage Regulator with Power Good

Description: The NCV4290 is an integrated low dropout regulator...
  • The NCV4290 is an integrated low dropout regulator designed for use in harsh automotive enviroments. It includes wide operating temperature and input voltage ranges. The output is regulated at 5 V and is rated to 450 mA of output current.
    It also provides a number of features, including overcurrent protection, overtemperature protection and a programable microprocessor power good signal. The NCV4290 is available in the DPAK and D2PAK surface mount package. The output is stable over wide output capcitance and ESR range.
  • Features
  • 5.0 V, 2% Output Voltage Accuracy with 450 mA Output Current - Can operate with newest microprocessor.
  • 500 mV (max) Dropout Voltage - Can operate during cranking at low input voltage.
  • Active Power Good Output
    Power Good Low Down to VQ = 1.0 V - Integrated control of microprocessor power supply - lower cost and space
  • Fault Protection
    +45 V Peak Transient Voltage
    -42 V Reverse Voltage
    Short Circuit Protection
    Thermal Overload Protection - No external components required to enable protections required within any automotive applications.
