Microchip Technology, Inc. Dual LDO with Microcontroller Reset Function en010640

The TC1301A/B combines two Low Drop Out (LDO) regulators and a microcontroller RESET function while the TC1302A/B is purely a dual LDO. Both parts are available in single 8-pin MSOP or DFN package. The TC1301A/B & TC1302A/B features low dropout voltages as low as 104mV @ 300mA, low quiescent current consumption at 116 µA typical and a voltage output accuracy of +/- 0.5%. Several fixed output voltage and detector voltage combinations are available. A reference bypass pin is available for TC1301A/B to further reduce output noise and improve the power supply rejection ratio of both LDOs. The TC1301A/B & TC1302A/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. Additional Features Dual Output LDO with Microcontroller Reset Monitor Output Voltage and RESET Threshold Voltage Low Dropout Voltage Low Supply Current: 116 µA, Typical Reference Bypass Input for Low Noise Operation Both Output Voltages Stable with a Minimum of 1 µF Ceramic Output Capacitor Separate Input for RESET Detect Voltage RESET Output Duration: 300 msec. Typical Power Saving Shutdown Mode of Operation Wake up from SHDN: 10 µsec,Typical Small 8-pin DFN and 8-pin MSOP Package Operating Junction Temperature Range: -40°C to +125° Over Temperature and Over Current Protection
