All four LDOs have independent shutdown inputs and
can be programmed using two select inputs making the
TC1307 adaptable for a wide range of multiple output
applications. The tri-state SELECT12 input pin allows
the designer to select the output voltages on VOUT1,
and VOUT2 from three different values (2.5V, 2.8V or
3.0V). The tri-state SELECT34 input pin allows the
designer to select the output voltages on VOUT3, and
VOUT4 from three different values (1.8V, 2.5V or 2.8V).
All four LDO’s require only a 1 μF output capacitor for
stability that can be ceramic, tantalum or aluminum
over the entire input voltage operating range and 0 mA
to 150 mA rated load range. All four LDOs have low
output noise and excellent dynamic response when
faced with sudden line and load changes.
The voltage detect pin is set for a threshold of 2.63V
(typical) and operates down to a minimum input voltage
of 1.0V. When the voltage on the detect pin rises above
the 2.63V threshold, the RESET output is held low for
300 ms (typical).
Additional integrated features include over-current protection
and over-temperature protection providing full
protection from external load faults.
