NCV8508B

NCV8508B LDO Regulator - Watchdog, RESET 5.0 V, 3.3 V, 250 mA The NCV8508B is a precision micropower Low Dropout (LDO) voltage regulator. The part contains many of the required features for powering microprocessors. Its robustness makes it suitable for severe automotive environments. In addition, the NCV8508B is ideal for use in battery operated, microprocessor controlled equipment because of its extremely low quiescent current. Features Output Voltage: 5.0 V and 3.3 V ±3.0% Output Voltage IOUT Up to 250 mA Quiescent Current Independent of Load Micropower Compatible Control Functions: ♦ Wakeup ♦ Watchdog ♦ RESET Low Quiescent Current (100 mA typ) Protection Features: ♦ Thermal Shutdown ♦ Short Circuit ♦ 45 V Operation NCV Prefix for Automotive and Other Applications Requiring Site and Change Controls AEC Qualified PPAP Capable These are Pb−Free Devices Microprocessor MRA4004T3 VBAT NCV8508B C1* VIN 0.1 mF VOUT WDI Delay RESET RDelay 60 k WAKEUP GND C2 VDD 1.0 mF I/O RESET I/O http://onsemi.com MARKING DIAGRAMS D2PAK−7 DS SUFFIX CASE 936AB V8508yBxx AWLYWWG 1 8 1 SO−8 EP PD SUFFIX CASE 751AC 8 508yBx ALYW G 1 xx, x = Voltage Option 5.0 V (xx = 50, x = 5) 3.3 V (xx = 33, x = 3) y = Timing Option (see Page 4 for more details) 1 (Delay Time = 3 ms @ RDelay = 60k) 2 (Delay Time = 9 ms @ RDelay = 60k) A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week G or G = Pb−Free Package ORDERING INFORMATION See deta...
