TC55 Series
1µA LOW DROPOUT POSITIVE VOLTAGE REGULATOR
FEATURES
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 differential of 380mV at 200mA.
The low dropout voltage combined with the low current
consumption of only 1.1µA 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
VIN – VOUT differentials.
The circuit also incorporates short-circuit protection to
ensure maximum reliability.
