500mA Output LDO Regulator with Voltage Detector - BD42754FP2-C

BD42754FP2-C is automotive suited voltage regulator with 1ch Reset and offers the output current of 500mA while limiting the low quiescent current. This regulator is therefore ideal for applications requiring a direct connection to the battery and a low current consumption. A reset signal is generated for an output voltage VO of Typ 4.62 V. The reset delay time can be programmed by the external capacitor.
