Developed specifically for battery powered portable applications, all four out- puts of the TC1307 typically consume a total of 220 µA supply current, hold the output voltage to a tolerance of 0.5% and require 100 mV of headroom for regulation at the maximum output current of 150 mA. In addition to the four high performance LDOs, the TC1307 also includes a voltage detector with a delayed RESET out- put that can be configured for low battery detection or Microcontroller Reset Generator. 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 pro- tection and over-temperature protection providing full protection from external load faults.
