LM337IMP/NOPB +BOM

Negative Adjustable Regulator

LM337IMP/NOPB General Description

The LM337IMP/NOPB is a three-terminal adjustable negative voltage regulator capable of providing output voltages from -1.2V to -37V at currents up to 100mA. It is manufactured by Texas Instruments and comes in an SOT-223 package. The device requires only two external resistors to set the output voltage, making it easy to use in various applications. Its adjustable output voltage makes it suitable for use in many different circuits where a negative voltage reference is required. The LM337IMP/NOPB features thermal overload protection and short-circuit current limiting to ensure reliable operation under various conditions. With its wide operating temperature range and low dropout voltage, it is commonly used in power supply circuits, voltage regulators, and voltage reference applications.
