The TC1305 combines two CMOS Low Dropout Regulatorsand a Microprocessor Monitor in a space saving10-Pin MSOP package. Designed specifically forbattery operated systems, total supply current istypically 120μA at full load, 20 to 60 TImes lower than inbipolar regulators.The TC1305 features selectable output voltages forhigher design flexibility. The tri-state SELECT input pinallows the user to select VOUT1 and VOUT2 from 3different values (2.5V, 2.8V and 3.0V).An acTIve low RESET is asserted when the detectedvoltage (VDET) falls below the 2.63V reset voltagethreshold. The RESET output remains low for 300msec(typical) after VDET rises above reset threshold. Whenthe shutdown controls (SHDN1 and SHDN2) are low,the regulator output voltages fall to zero, RESET outputremains valid and supply current is reduced to 20μA(typ.)Other key features for the device include ultra low noiseoperaTIon, fast response to step changes in load andvery low dropout voltage (typically 150mV at full load).The device also incorporates both over temperatureand over current protecTIon. Each regulator is stablewith an output capacitor of only 1μF and has amaximum output current of 150mA. The TC1305 isfeatured in a 10-Pin MSOP package with selectiveoutput voltages.
