TB9000AFG Datasheet, PDF (1/11 Pages) Toshiba Semiconductor – 5 V Voltage Regulator with Watchdog Timer

TOSHIBA BiCMOS Integrated Circuit Silicon Monolithic
TB9000AFG
5 V Voltage Regulator with Watchdog Timer
TB9000AFG
The TB9000AFG is an IC specially designed for microcomputer
systems in automobiles. It features low standby current and
various system reset functions.
With an external pass Tr., the TB9000AFG can supply a high
output current. A current limiter function is incorporated as a
protective function.
System reset includes low-voltage reset, power-on reset, and
watchdog timer functionality.
Weight: 0.14 g (typ.)
