TC1305

TC1305 Dual 150mA CMOS LDO With Select Mode™ Operation, Shutdown and Independent RESET Output Features Extremely Low Supply Current for Longer Battery Life Select Mode™ Operation: Selectable Output www.DataSheet4U.com Voltages for High Design Flexibility Very Low Dropout Voltage 29µVRMS Typical Output Noise 10µsec (Typ.) Wake-Up Time from SHDN 150mA Output Current per Output High Output Voltage Accuracy Power-Saving Shutdown Mode RESET Output Can Be Used as a Low Battery Detector or Processor Reset Generator Over Current Protection and Over Temperature Shutdown Space Saving 10-Pin MSOP Package General Description The TC1305 combines two CMOS Low Dropout Regulators and a Microprocessor Monitor in a space saving 10-Pin MSOP package. Designed specifically for battery operated systems, total supply current is typically 120µA at full load, 20 to 60 times lower than in bipolar regulators. The TC1305 features selectable output voltages for higher design flexibility. The tri-state SELECT input pin allows the user to select VOUT1 and VOUT2 from 3 different values (2.5V, 2.8V and 3.0V). An active low RESET is asserted when the detected voltage (V DET) falls below the 2.63V reset voltage threshold. The RESET output remains low for 300msec (typical) after VDET rises above reset threshold. When the shutdown controls (SHDN1 and SHDN2) are low, the regulator output voltages fall to zero, RESET output remains valid and supply current is reduced to 20µA (typ.) Other key...
