STMicroelectronics' model L7815CV (click to buy now) is a voltage regulator chip that comes in a TO-220 package and several fixed output voltages, and can be used in a wide range of applications. These regulators can provide local on-card supervision, eliminating the distribution issues associated with single-point supervision. Each type has internal current limiting, thermal shutdown, and safe area protection embedded in it, making it essentially indestructible. If sufficient heat dissipation is provided, they can provide output current in excess of 1A. Although these devices are primarily designed as fixed voltage regulators, they can be used with external components to obtain adjustable voltage and current.
