Microchip Technology

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.

The TC1302A combines two Low Dropout (LDO) regulators into a single 8-pin MSOP or DFN package. Both regulator ouputs feature low dropout voltage, 104 mV @ 300 mA for Vout1, 150 mV @ 150 mA for Vout2, low quiescent current consumption, 58 µA each and a typical regulation accuracy of 0.5%. Several fixed-output 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 TC1303C combines a 500mA synchronous buck regulator and a 300mA low-dropout (LDO) regulator with a power-good monitor to provide a highly integrated solution for applications that require multiple supply voltages. The power-good function monitors the outputs of the Buck and LDO regulators.

The TC1304 combines a 500mA synchronous buck regulator and a 300mA low-dropout (LDO) regulator with a power-good monitor to provide a highly integrated solution for applications that require multiple supply voltages. The power-good function monitors the outputs of the Buck and LDO regulators and can provide sequenced startup and shutdown.

The TC1307 combines four CMOS Low Dropout Regulators and a Microprocessor Monitor in a space-saving 16-Pin QSOP package. Designed specifically for battery-operated systems, the device’s CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current for this device is typically 220µA at full load on all four LDO channels. The TC1307 features selectable output voltages for higher design flexibility. The SELECT Mode pins allows the user to select from 4 different values (1.8V, 2.5V, 2.8V and 3.0V). An active low RESET is asserted when the output voltage VOUT2 falls below the 2.63V reset voltage threshold. Other key features for the device include ultra low-noise operation, fast response to step changes in load, and very low dropout voltage, typically 165mV at full load. The device also incorporates both over-temperature and over-current protection. Each regulator is stable with an output capacitor of only 1µF and has a maximum output current of 150mA.

The TC1321 is a serially accessible 10-bit voltage output digital-to-analog converter (DAC). The DAC produces an output voltage that ranges from ground to an externally supplied reference voltage. It operates from a single power supply that can range from 2.7V to 5.5V, making it ideal for a wide range of applications. Built into the part is a power-on reset function that ensures that the device starts at a known condition. Communication with the TC1321 is accomplished via a simple 2-wire SMBus/I2C™ compatible serial port with the TC1321 acting as a slave only device. The host can enable the SHDN bit in the CONFIG register to activate the low-power standby mode.

The TC1410/1410N are 0.5 A CMOS buffer/gate drivers. They will not latch up under any conditions within their power and voltage ratings. They are not subject to damage when up to 5 V of noise spiking of either polarity occurs on the ground pin. They can accept, without damage or logic upset, up to 500 mA of current of either polarity being forced back into their output. All terminals are fully protected against up to 4 kV of electrostatic discharge. As MOSFET gate drivers, the TC1410/1410N can easily switch 500 pF gate capacitance in 25 ns with matched rise and fall times, and provide low enough impedance in both the ON and the OFF states to ensure the MOSFET’s intended state will not be affected, even by large transients. The rise and fall time edges are matched to allow driving short-duration inputs with greater accuracy.

The TC1411/1411N are 1 A CMOS buffer/gate drivers. They will not latch up under any conditions within their power and voltage ratings. They are not subject to damage when up to 5 V of noise spiking of either polarity occurs on the ground pin. They can accept, without damage or logic upset, up to 500 mA of current of either polarity being forced back into their output. All terminals are fully protected against up to 4 kV of electrostatic discharge. As MOSFET drivers, the TC1411/1411N can easily switch 1,000 pF gate capacitance in 25 ns with matched rise and fall times, and provide low enough impedance in both the ON and the OFF states to ensure the MOSFET’s intended state will not be affected, even by large transients. The rise and fall time edges are matched to allow driving short-duration inputs with greater accuracy.
