Features - - - .. - - - - - - - - - - Four Independent 150 m A LDOs Low Supply Current (220 µA typical) High Output Voltage Accuracy (0.5% typical) Low Dropout Voltage (100 m V typical with 150 m A load) Four Independent Shutdown Inputs Select Mode™: Selectable Output Voltages for High Design Flexibility Integrated Independent Microprocessor Reset Low Noise Outputs Fast Response from Shutdown (10 µs typical) RESET Output for Low Battery Detection or Reset Generator Over Current and Over-Temperature Protection Small 16-Pin QSOP Package Specified Junction Temperature Range: - -40°C to +125°C 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 m A to 150 m A 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.
