FEATURES

I Very Low Dropout Voltage .... 120mV typ at 100mA 380mV typ at 200mA (± 1% Semicustom Version) 3-Pin SOT-89 I Short Circuit Protection I Custom Voltages Available from 1.1V to 6.0V in 0.1V Steps for a 2%, and 2.0V to 6.0V for a 1% Tolerance

APPLICATIONS

I Cameras and Portable Video Equipment I Pagers and Cellular Phones I Solar-Powered Instruments I Consumer Products 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 1.1µA 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 V IN – VOUT differentials. The circuit also incorporates short-circuit protection to ensure maximum reliability. 1µA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Output Voltage: Extra Feature Code: Fixed: 0 Tolerance: 1 = 1.0% (Custom) 2 = 2.0% (Standard) Temperature: E: – 40°C to +85°C Package Type and Pin Count: CB: 3-Pin SOT-23A (equivalent to EIAJ SC-59) MB: 3-Pin SOT-89 Taping Direction: TR or 713: Standard Taping RT or 723: Reverse Taping PART CODE TC55 RP XX X X X XX XXX
