1 TC55 Series LOW DROPOUT POSITIVE VOLTAGE REGULATOR 2 GENERAL DESCRIPTION FEATURES The TC55 Series is a collection of CMOS low dropout Very Low Dropout Voltage .... 120mV typ at 100mA positive voltage regulators which can source up to 250mA of 380mV typ at 200mA current with an extremely low input-output voltage differen- High Output Current .............. 250mA (VOUT = 5.0V) tial of 380mV. High Accuracy Output Voltage ........................± 2% The low dropout voltage combined with the low current (± 1% Semicustom Version) consumption of only 1.1µA makes this part ideal for battery Wide Output Voltage Range .................... 2.1V-6.0V 3 operation. The low voltage differential (dropout voltage) Low Power Consumption ................... 1.1µA (Typ.) ex
