LDO Regulator with base terminal for Current Boost
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
An external transistor can be used.
(Base current Typ10mA)
