ILE4278

ILE4278 5-V Low-Drop Fixed Voltage Regulator Functional Description The IZE4278 (functional equivalent of TLE4278 G Infineon) is a monolithic integrated lowdrop fixed-voltage regulator 5V/150mA with low current consumption and additional functions for automotive electronics The IZE4278 is available in chip form and suitable for assembly in SO-20 package. The IZE4278 provides output positive voltage 5V ± 2 % (under load current up to 150mA and supply voltage range 6 to 28V) and 5V ± 4 % (under load current up to 50mA and supply voltage range 28 to 45V)/ Drop voltage not exceed 0,5V under load current 100mA. The IZE4278 is steady to overvoltage of both (positive and negative) polarities, short-circuit of output to ground., contain internal limiting circuit of load current and thermal shutdown. It is equipped with additional functions such as reset, reset parameters adjustment, watchdog circuit with input of activation threshold adjustment. The IZE 4278 can be used in power supply sources of electronic devices and particularly in automotive electronics Features Precision output voltage5V ± 2% Very low current consumption Low-drop voltage Watchdog Adjustable watchdog activating threshold Settable reset threshold Overheating protection Reverse polarity protection Short-circuit proof Wide temperature range 40 to +125°С Suitable for use in automotive electronics Block diagram.
