The TK715xx is a low dropout linear regulator from Toko. It is housed in a small SOT23-3 package and rated at 400 mW. It has a low dropout voltage of 105 mV (typ.) at 50 mA load current and an output voltage accuracy of ± 2.0% or ± 60 mV. The TK715xx has a very low quiescent current of 25 µA (typ.) at no load.
The TK715xxAS is a low‑dropout linear regulator designed for battery‑powered systems and portable equipment. It offers high‑precision output voltage (+2.0 % or +60 mV), very low quiescent current (25 µA typ.) and internal reverse‑bias protection, eliminating the need for an external diode.
The device is supplied in a miniature SOT‑23‑3 package, rated for 400 mW power dissipation. Key electrical characteristics include a typical dropout voltage of 105 mV at 50 mA load, 60 dB ripple rejection, and an operating temperature range of –30 °C to +80 °C. The datasheet also details ordering codes, pin definitions, and typical performance curves.
