MC7809BT Description

Short technical summary and product information.

The ON Semiconductor MC7809BT is a versatile linear voltage regulator designed for a wide range of applications requiring a stable 9V output. This device is capable of delivering output currents in excess of 1A and requires no external components for basic operation.

 

Key electrical characteristics include a nominal 9V output voltage, a maximum input voltage of 35V, and a typical quiescent current of 8mA. It also provides Power Supply Ripple Rejection (PSRR) of 61dB at 120Hz. Protection features include internal thermal overload protection and short-circuit current limiting, enhancing reliability.

 

The MC7809BT is supplied in a standard TO-220-3 package, suitable for through-hole mounting. It operates within a temperature range of -40°C to 125°C. The device also includes ESD protection, rated for 2000V (HBM) and 200V (MM).

 

This regulator is well-suited for local on-card regulation and various power supply applications where a fixed positive voltage is required.
