DETAILED DESCRIPTION
The TC1306 is a precision fixed output voltage
regulator that contains two fully independent 150mA
outputs. The device also features separate shutdown
modes for low-power operation. The Select Mode
operation allows the user to select V
OUT2
from two
different values (2.8V, 3.0V), therefore providing high
design flexibility. V
OUT1
supplies a fixed 1.8V output
voltage. The CMOS construction of the TC1306 results
in a very low supply current, which does not increase
with load changes. In addition, V
OUT
remains stable
and within regulation at no load currents.
The TC1306 also features an integrated microproces-
sor supervisor that monitors the V
OUT2
output. The
active low RESET signal is asserted when the voltage
of V
OUT2
falls below the reset voltage threshold
(2.63V). The RESET output remains low for 300msec
(typical) after V
OUT2
rises above the reset threshold.
The RESET output of the TC1306 is optimized to reject
fast transient glitches on the monitored output line.
