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™

different values (2.8V, 3.0V), therefore providing high

voltage. The CMOS construction of the TC1306 results

in a very low supply current, which does not increase

and within regulation at no load currents.

The TC1306 also features an integrated microproces-

active low RESET signal is asserted when the voltage

(2.63V). The RESET output remains low for 300msec

The RESET output of the TC1306 is optimized to reject

fast transient glitches on the monitored output line.
