TA8045BF
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHI
TA8045BF
5V Voltage Regulator With Watchdog Timer
This IC is designed especially for microcomputer system in
automobiles and is capable of providing output voltage 5 ±0.15V
without any adjustment.
This IC incorporates the system reset function, that is, low
voltage reset and watchdog timer which can self-diagnose the
microcomputer system so that program runaway can be
prevented.
This IC also has an over-voltage protection, current limiter and
thermal protection to protect the IC from destruction caused of
overstress and load accident.
In addition, this IC has a low standby current function, so it can
be connected directly to an automotive battery.
Weight: 0.14 g (typ.)
FEATURES
l Operating DC Supply Voltage Range : 6~30V
l Transient Supply Voltage : 60V (Max.)
l Extremely low Quiescient Current in Standby Mode : 400μA (Max.)
