550mA Output LDO Regulator with WDT and Voltage Detector - BD4271FP2-C
BD4271FP2-C is automotive voltage regulator with watchdog timer and offers the output current of 550mA while limiting the quiescent current low. A logical “HIGH” at the CTL pin enables the LDO regulator and “LOW” disables the LDO regulator and keeps current consumption low. A reset signal is generated for an output voltage VO of Typ 4.65V. The reset delay time and watchdog time (WDT) can be programmed by the external capacitor.
