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. APPLICATIONS
Electronic Equipment Battery Powered Systems
Mobile communications, etc.
