Both regulator outputs feature low dropout voltage, 104 mV @300 mA for VOUT1, 150mV @ 150mA for VOUT2, low quiescent current consumption, 58 µA each and a typical regulation accuracy of 0.5%. Several fixed- output voltage and detector voltage combinations are available. A reference bypass pin is available to further reduce output noise and improve the power supply rejection ratio of both LDOs. The TC1301A/B is stable over all line and load conditions with a minimum of 1 µF of ceramic output capacitance, and utilizes a unique compensation scheme to provide fast dynamic response to sudden line voltage and load current changes. For the TC1301A, the microcontroller RESET function operates independently of both VOUT1 and VOUT2. The input to the RESET function is connected to the VDET pin.The SHDN2 pin is used to control the output of VOUT2 only. VOUT1 will power-up and down with VIN. In the case of the TC1301B, the detect voltage input of the RESET function is connected internally to VOUT1. Both VOUT1 and VOUT2 have independent shutdown capability. Additional features include an overcurrent limit and overtemperature protection that, when combined, provide a robust design for all load fault conditions.
