Description
TK714xxS LDO Regulator with base terminal for Current Boost TK714xxS 1. DESCRIPTION The TK714xxS is a low dropout linear regulator with internal PNP pass transistor that can supply 100mA load current. The phase compensation in the IC has been optimized that the output capacitor can be omitted. The TK714xxS is provided with the On/Off control function and also with the base terminal for the external transistor that 1A low dropout regulator can be easily composed by connecting external transistor (Hfe around 100). 2. FEATURES „An external transistor can be used. (Base current Typ10mA) „ On/Off control available (High ON). „ No input current at Off mode „Excellent output stability (CL 0.022µF,Iout 2mA) „High ripple rejection (-70dB at 1kHz) „100mA load current guarantee „Output voltage available from 1.3 to 5.0V (0.1V step). 3.
