LM337IMPX/NOPB

PMIC - Voltage Regulators - Linear

The LM337IMPX/NOPB is a type of voltage regulator, specifically a linear voltage regulator. It is a monolithic integrated circuit construction of a 3-terminal adjustable negative voltage regulator, with a range of 1.2 to -37V, and a maximum output current capability of 1.5 A.

Linear voltage regulators work by providing a relatively constant output voltage even under varying input voltages and varying load currents. They operate by using a built-in voltage reference and an error amplifier to sense small differences between an external reference voltage and the output voltage. These small differences are amplified and used to adjust the gate on an pass element, so that the output voltage is maintained relatively constant.

Application Fields for the LM337IMPX/NOPB

The LM337IMPX/NOPB voltage regulator can be used in a range of applications, from power supplies, to battery chargers, to automotive systems. It is particularly well-suited to use in applications where a low-power, programmable, low-dropout voltage regulator is needed.

The LM337IMPX/NOPB is also useful for applications where a negative supply line is needed. The ability of the regulator to output a negative voltage, as low as -37V, makes it an ideal choice for negative power supplies. This can be especially useful in automotive-related applications.
