NCV4949A/D
NCV4949A
100 mA, 5.0 V, Low Dropout
Voltage Regulator with
Reset and Sense
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
• Operating DC Supply Voltage Range 5.0 V to 28 V
• Transient Supply Voltage Up to 40 V
• High Precision Output Voltage 5.0 V ±1%
• Output Current Capability Up to 100 mA
• Very Low Dropout Voltage Less Than 0.4 V
• Reset Circuit Sensing The Output Voltage
• Programmable Reset Pulse Delay
• Voltage Sense Comparator
• Thermal Shutdown and Short Circuit Protections
• AEC−Q100 Grade 1 Qualified and PPAP Capable
• These are Pb−Free Devices
