TA8044AF
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8044AF
3.3V / 5V DUAL-VOLTAGE REGULATOR WITH WATCHDOG TIMER
Designed specifically for use in 3.3V microcomputers, this IC
contains two constant-voltage power supplies for 3.3V and 5V
uses and various system reset functions.
This IC's Power Supply Output 1 provides an output voltage of
3.4V and contains an output transistor capable of producing
10mA of output current. With an external boost transistor
connected, this IC can supply a large output current. A 150mA
current limiter is included.
Power Supply Output 2 provides an output voltage of 5.0V which
can be turned on or off from the EN pin. This output uses an
external output transistor. Any desired current limiter value can
be set using an external adjusting resistor.
For a system reset, it has a low-voltage monitor / power-on reset /
watchdog timer at Power Supply Output 2.
Weight: 0.14 g (typ.)
