The TA78DS series includes a family of low‑dropout, positive‑fixed output voltage regulators (TA78DS05, TA78DS06, TA78DS08, TA78DS09, TA78DS10, TA78DS12, TA78DS15, and TA78DS05CP) capable of delivering up to 30 mA. They are designed for battery‑powered equipment and feature low standby current, over‑voltage, thermal‑shutdown, reverse‑polarity and current‑limiting protection.
Key specifications such as maximum ratings, electrical characteristics, and typical application circuits are listed, along with a block diagram and outline drawing of the TO‑92 package. The document also notes recommended external components, such as a 100 µF capacitor for output stability.
| Maximum Output Current | 30 mA |
|---|---|
| Low Dropout Voltage | < 0.3 V |
| Low Standby Current | 600 µA (typical) |
| Operating Input Voltage (VIN) | 29 V |
| Input Surge Voltage | 60 V |
| Operating Temperature Range | -40 °C to 85 °C |
| Thermal Resistance (junction‑to‑ambient) | 156 °C/W |
The TA78DS series can source up to 30 mA of output current.
The dropout voltage is less than 0.3 V.
The devices provide reverse‑connection protection, overload protection, thermal shutdown, and current limiting.
It is available in a plastic TO‑92 MOD package.
