DESCRIPTION
The TK715xx is a low dropout linear
regulator housed in a small SOT-23-3 package, rated at 350 mW. An internal
PNP transistor is used to achieve a low dropout voltage of 105 mV (typ.) at 50 mA load current. This device offers high precision output voltage of ± 2.0 % or ± 60 mV. The TK715xx has a very low quiescent current of 25 µA (typ.) at no load. The low quiescent current and dropout voltage make this part ideal for battery powered applications. The internal reverse bias protection eliminates the requirement for a reverse voltage protection diode, saving cost and board space. The high 64 dB ripple rejection and low noise provide enhanced performance for critical applications.
