( Part Type: Voltage Regulator ), ( Country/region Of Manufacture: Unknown )
The 276-1779 Negative Voltage Regulator LM337T, a product available from Radioshack as a "No- Stock" (NOS) item, is a versatile and widely-used electronic component that provides stable, regulated voltage output in a compact package. This particular part is a Texas Instruments LM337T, a variant of the popular LM337 series of three-terminal linear voltage regulators.
The LM337T is a fixed-voltage regulator, capable of delivering a regulated output voltage between 1.2V and 37V, with a typical dropout voltage of 2V at no load. This makes it suitable for use with a wide range of power supplies and load requirements. The negative polarity of the output voltage, indicated by the 'T' in the part number, means that it can be used to supply power to negative-voltage circuits or to regulate the voltage of a battery-powered system, such as a radio, flashlight, or digital watch.
The 276-1779 LM337T is a through-hole device, meaning it can be easily mounted on a printed circuit board (PCB) using traditional soldering techniques. It has a compact footprint of 8mm x 3mm, making it a suitable choice for space-constrained designs. The device operates over a wide temperature range of -55 C to 150 C, ensuring reliable operation in a wide variety of environments.
The LM337T is known for its low noise output, typically less than 15mV RMS, which makes it suitable for use in audio and other high-sensitivity applications. It also has a high input voltage capability, which allows it to operate from a wide range of power supplies, including unregulated or noisy sources. The regulator has a current output rating of up to 1.5A, which is more than sufficient for most low-power applications.
In summary, the 276-1779 Negative Voltage Regulator LM337T is a high-performance, versatile, and compact voltage regulator that can be used in a wide variety of applications. Its fixed-voltage output, wide operating temperature range, low noise, and high input voltage capability make it a popular choice for hobbyists, engineers, and professionals in the fields of electronics, radio, and digital technology.
