Texas Instruments LM337KCSE3 Adjustable Negative Linear Voltage Regulator, TO-

The Texas Instruments LM337KCSE3 is a high-performance, 3-terminal adjustable negative linear voltage regulator, designed to deliver a robust and stable power supply solution. It is capable of supplying in excess of 1.5A over a wide, adjustable output voltage range from -1.2V to -37V. This makes it an exceptionally versatile component for designing and stabilising negative voltage rails in a variety of electronic circuits.

A key advantage of this regulator is its simplicity of use. It requires only two external resistors to set the precise output voltage and a single non-ceramic output capacitor for effective frequency compensation, minimising the bill of materials and simplifying board layout. The device exhibits excellent regulation characteristics, including a very low 0.01% line regulation and 0.3% load regulation, ensuring a consistent output despite variations in input voltage or load current.

Engineered for reliability, the LM337KCSE3 maintains a peak output current that is constant over its full operating temperature range. It also offers a typically high 77dB ripple rejection, effectively filtering out noise and ripple from the input supply to deliver a clean, stable DC output. Housed in a robust TO-220 through-hole package with 3 pins, it is designed for easy mounting and provides efficient thermal dissipation for demanding applications.
