TA79L09F Description

Short technical summary and product information.

The TA79L09F from Toshiba is a monolithic integrated circuit designed as a three-terminal negative output voltage regulator. It is suitable for a wide range of applications, including TTL and C2MOS power supplies, due to its fixed -9V output voltage. The device requires no external components for operation and includes built-in overcurrent and thermal protection circuits.

Key electrical characteristics include an output voltage of -9V (typical), with a maximum input voltage of -40V and a maximum power dissipation of 500mW at 25°C. The operating temperature range is from -30°C to 85°C. The regulator is available in a power mini SOT-89 package, making it suitable for space-constrained designs.

With a maximum output current capability of 150mA at 25°C, the TA79L09F provides a reliable and efficient solution for power regulation needs. Its internal circuitry ensures stable operation with features like input and load stability, bias current regulation, and ripple rejection.
