Datasheet LDO Regulators with Voltage Detector 500 mA Output LDO Regulator with Voltage Detector BD4275FP2-C BD4275FPJ-C General Description Key Specifications BD4275FP2-C and BD4275FPJ-C are automotive suited Qualified for Automotive Applications voltage regulator with 1ch Reset and offers the output Input Voltage Range: -0.3 V to +45 V current of 500mA while limiting the low quiescent current. Low Quiescent Current: 65 A (Typ) These regulators are therefore ideal for applications Output Load Current: 500 mA requiring a direct connection to the battery and a low Output Voltage: 5.0 V 2 % current consumption. A reset signal is generated for an Reset Detect Voltage : 4.50 V to 4.75 V output voltage VO of Typ 4.62 V. Over Current Protection (OCP) The reset delay time can be programmed by the external Thermal Shut Down (TSD) capacitor. Package W (Typ) D (Typ) H (Max) Features FP2: TO263-5F 10.16 mm 15.10 mm 4.70 mm (1) AEC-Q100 qualified. Low ESR ceramic capacitors applicable for output. Low drop voltage: PDMOS output transistor Power on and under-voltage reset Programmable reset delay time by external capacitor.
