GENERAL DESCRIPTION

The TC55 Series is a collection of CMOS low dropout

positive voltage regulators which can source up to 250mA of

current with an extremely low input-output voltage differen-

tial of 380mV at 200mA.

The low dropout voltage combined with the low current

consumption of only 1.1

µA makes this part ideal for battery

operation. The low voltage differential (dropout voltage)

extends battery operating lifetime. It also permits high

currents in small packages when operated with minimum

The circuit also incorporates short-circuit protection to

ensure maximum reliability.
