Description

The TC1307 combines four CMOS Low Dropout Linear Regulators with a Microcontroller Monitor in a spacesaving 16-Pin QSOP package. Developed specifically for battery powered portable applications, all four outputs of the TC1307 typically consume a total of 220 µA supply current, hold the output voltage to a tolerance of 0.5 and require 100 mV of headroom for regulation at the maximum output current of 150 mA.
