Datasheet LDO Regulators with Voltage Detector 200mA / 300mA Output LDO Regulator with 2ch RESET BD4269FJ-C BD4269EFJ-C General Description Key Specifications BD4269FJ-C BD4269EFJ-C are a low quiescent Qualified for Automotive Applications voltage regulator with 45V absolute maximum voltage Input voltage range: -0.3 to +45 V allowing usage in battery direct-connected systems. IC Low quiescent current: 70 A (Typ) integrates Power on and under-voltage reset and Input Output load (BD4269FJ-C): 200 mA voltage reset for VCC or other voltages. Quiescent (BD4269EFJ-C) 300 mA current is minimized to optimize the system current Output voltage: 5.0 V 2 % consumption. Offers selection of the output current Power on and under-voltage reset detect voltage: between 200 mA or 300 mA depending on the 4.62 V 2.6 % application. (Adjusting detect voltage accuracy:3 %) Power on and under-voltage reset and Input voltage Over Current Protection (OCP) reset threshold voltage can be adjusted by external Thermal Shut Down (TSD) resistance. Power on and under-voltage reset delay time can programmed set by external capacitor. Packages W (Typ) x D (Typ) x H (Max) Features FJ: SOP-J8 4.90 mm x 6.00 mm x 1.65 mm (Note 1) AEC-Q100 Qualifies Low ESR ceramic capacitors applicable for output. Low drop voltage: PDMOS output transistor Power on and under-voltage reset Sense input comparator for VCC or other voltage EFJHTSOP-J8 4.90 mm x 6.00 mm x 1.00 mm Adjustable power on and under-voltage reset and Sense input comparator by external resistance Programmable reset delay time by external capacitor.
