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

µAat full load, 20to60times lower thaninbipolar

regulators.

The TC1306 features selectable output voltages for

higher design flexibility. The dual-state SELECT input

pin allows the user to select VOUT2 from 2 different

values (2.8V and 3.0V). VOUT1 supplies a fixed 1.8V

voltage.

An active low RESET is asserted when the output

voltage VOUT2 falls below the 2.63V reset voltage

threshold. The RESET output remains low for 300msec

(typical)afterVOUT2 rises above reset threshold. When

the shutdown control (SHDN1) is low, the regulator

output voltage VOUT1 falls to zero and RESET output

remains valid. When the shutdown control (SHDN2)is

low, the regulator output voltage VOUT2 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

µF and has a

maximum output current of 150mA.
