TC55 Series 1A 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 1.1A 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.
