Product Description


LD4263 is a 5-V low drop voltage regulator. The maximum input voltage is 45 V. The maximum output current is more than 200 mA. The IC is short-circuit proof and incorporates temperature protection which turns off the IC at over temperature.



The IC regulates an input voltage VI in the range of 6V < VI < 45V to VQ,nom = 5.0V. A reset signal is generated for an output voltage of VQ, rt < 4.5V. This voltage threshold can be decreased to 3.5V by external connection of a voltage divider. The reset delay can be set externally by a capacitor. The integrated watchdog logic supervises the connected micro controller. The IC can be switched off via the inhibit input, which causes the current consumption to drop from 900 ¼A to typical 0¼A.
