Q & A

The L7809CV 9V Voltage regulator can provide local on-card regulation, eliminating the distribution problems associated with single-point regulation. It employs internal current limiting, thermal shutdown and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, it can deliver over 1.5A output current. Although designed primarily as a fixed voltage regulator, this device can be used with external components to obtain adjustable voltages and currents.

STMicroelectronics L78 Series of fixed output voltage regulators are useful in a wide range of electronics industry applications. The three-terminal positive linear voltage regulators can remove problems related to single point regulation by providing local on-card regulation. The ST Regulator IC can deliver up to 1.5A at the fixed output voltage, ranging from 5 V to 24 V. The voltage regulator offers safe area protection with the addition of internal thermal shutdown and current limiting.
