MC79L05ACPRAG

MC79L05ACPRAG Description

The MC79L05ACPRAG from onsemi is a fixed-output negative linear voltage regulator delivering -5V at up to 100mA load current. Designed for precision voltage regulation in low-power circuits, it features a TO-92-3 through-hole package, making it suitable for prototyping and compact designs. With an operating temperature range of 0°C to 125°C, this regulator ensures stable performance across industrial and consumer applications. Its 49dB PSRR (120Hz) minimizes noise, while built-in over-temperature and short-circuit protection enhances reliability. The device complies with ROHS3 and REACH environmental standards and is supplied in Tape & Reel (TR) packaging for automated assembly.
