General Description
This device is a 5V low-drop fixed-voltage regulator. The maximum input voltage is 42V (65V, ≤400 ms). Up to an
input voltage of 26V and for an output current up to 550mA it regulates the output voltage within a 2% accuracy. The
short circuit protection limits the output current of more than 650mA. The device incorporates over voltage protection
and temperature protection that disables the circuit at un-permissibly high temperatures.
Features
● Output Voltage tolerance ≤±2%
● Low-drop Voltage
● Integrated Over Temperature Protection
● Reverse Polarity Protection
● Input Voltage up to 42V
● Over Voltage Protection up to 65V (≤400mS)
● Short-Circuit Proof
● Suitable for use in Automotive Electronics
● Wide Temperature Range
● Adjustable Reset Time
● ESD Protection > 4KV
