1 / 15 page March 2001 TOKO, Inc. Page 1 TK715xxAS BLOCK DIAGRAM TK715xxAS LOW DROPOUT VOLTAGE REGULATOR The TK715xx is a low dropout linear regulator housed in a small SOT23-3 package, rated at 400 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 60 dB ripple rejection and low noise provide enhanced performance for critical applications.
