Package Type
General Description
The TC1306 combines two CMOS Low Dropout Regu-
lators and a Microprocessor Monitor in a space saving
8-Pin MSOP package. Designed specifically for battery
operated systems, total supply current is typically
120
μ
A at full load, 20 to 60 times lower than in bipolar
regulators.
The TC1306 features selectable output voltages for
higher design flexibility. The dual-state SELECT input
pin allows the user to select V
OUT2
from 2 different
values (2.8V and 3.0V). V
OUT1
supplies a fixed 1.8V
voltage.
An active low RESET is asserted when the output
voltage V
OUT2
falls below the 2.63V reset voltage
threshold. The RESET output remains low for 300msec
(typical) after V
OUT2
rises above reset threshold. When
the shutdown control (SHDN1) is low, the regulator
output voltage V
OUT1
falls to zero and RESET output
remains valid. When the shutdown control (SHDN2) is
low, the regulator output voltage V
OUT2
falls to zero and
RESET output is low.
Other key features for the device include ultra low noise
operation, fast response to step changes in load and
very low dropout voltage (typically 125mV at full load).
The device also incorporates both over temperature
and over current protection. Each regulator is stable
with an output capacitor of only 1
μ
F and has a
maximum output current of 150mA.
