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.
The low dropout voltage combined with the low current
consumption of only 1.1
A makes this part ideal for battery
operation. The low voltage differential (dropout voltage)
extends battery operating lifetime. It also permits high cur-
rents in small packages when operated with minimum V
IN
V
OUT
differentials.
The circuit also incorporates short-circuit protection to
ensure maximum reliability.
