GENERAL DESCRIPTION

The TC55 Series is a family of CMOS low dropout positive voltage regulators which can source up to 250mA of current. The extremely low operating current (1.1µA typical) makes this part the ideal choice for battery operated applications and eliminates the need for an additional shutdown mode. The power consumption of the TC55 is 1000 times lower than in bipolar regulators, significantly extending battery life.
