TK115xx series devices are low power, linear regulators with electronic ON/OFF switches. Both active HIGH and active LOW control pins are provided. In order to achieve low dropout voltage (typically 200mV at 80 mA load current), an internal PNP pass-transistor is used. A base drive is available at pin 7 for connection of an external pass transistor should higher current (up to 1A) or lower dropout voltage is required.
The TK115xx series are low‑power linear regulators that include an electronic on/off switch. They are offered in a plastic SOP‑8 package and support both active‑HIGH and active‑LOW control pins. Variants cover output voltages from 3.0 V to 5.5 V and can deliver up to 100 mA continuous current.
Typical applications include cordless phones, pagers, battery‑powered systems, radio‑control devices, toys and other low‑voltage consumer equipment. The devices feature internal thermal shutdown, short‑circuit protection, and very low standby current (<200 nA).
| Typical dropout voltage | 200 mV at 80 mA load |
|---|---|
| Standby current (OFF mode) | <200 nA |
| Power dissipation | 600 mW |
| Storage temperature range | -55 °C to +150 °C |
| Operating temperature range | -30 °C to +80 °C |
| Package | SOP‑8 |
The typical dropout voltage is about 200 mV when delivering an 80 mA load.
The standby current in the OFF mode is less than 200 nA.
It is supplied in a plastic surface‑mount SOP‑8 package.
