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
μ
A 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

differentials.
The circuit also incorporates short-circuit protection to
ensure maximum reliability.
