Onsemi 12V 500mA Linear Voltage Regulator TO-252-3

Onsemi 12V 500mA Linear Voltage Regulator provides a fixed 12V positive output from an input range of 14V to 35V, with a maximum output current of 500mA.

This three-terminal linear voltage regulator is designed for efficient and reliable local, on-card voltage regulation. It operates in the same manner as the MC7800 series but is specified for a maximum output current of 500mA, making it suitable for applications where space and power requirements are more moderate.

Protective Features

The regulator includes internal current limiting, which safeguards the device against excessive current draw, and internal thermal overload protection, which automatically shuts the regulator down if temperatures become unsafe. Output transistor safe-area compensation further protects the internal pass transistor.

Performance

With a low output noise voltage of 75μV and a dropout voltage of 2 VDC, the regulator provides a stable 12V output. It requires no external components for basic operation, which simplifies circuit design.
