Product Description
STMicroelectronics L78S09CV is a robust 1-Channel Linear Voltage Regulator providing a fixed 9V output voltage up to 2A current capacity. Encapsulated in a TO-220 3-pin package, this linear regulator is designed for use in power management IC applications across industrial, electronic, embedded, and manufacturing environments.
The device offers reliable fixed voltage regulation with excellent line (130 mV) and load regulation (170 mV), ensuring consistent output voltage under varying load currents and input supply fluctuations. Its built-in protection features include thermal shutdown and output transition Safe Operating Area (SOA) protection to safeguard against over-temperature and short circuit conditions.
Operating within a wide temperature range from 0°C to 150°C and input voltage up to 35V, the L78S09CV is suitable for diverse thermal and voltage conditions. The positive polarity and fixed output configuration enable straightforward integration in electronic power supply designs.
The regulator features a low quiescent current of 8mA, reducing wasted power and heat dissipation, with a compact footprint measuring 10.4mm in length, 9.15mm in height, and 4.6mm in width. The TO-220 package provides easy PCB through-hole mounting and effective heat dissipation.
This STMicroelectronics product is ideal for use in industrial automation equipment, embedded system power supplies, consumer electronics, manufacturing machinery, and laboratory instrumentation requiring local on-card voltage regulation to improve power distribution stability and device longevity.
