Product Description
Texas Instruments LM337IMP/NOPB is an adjustable linear negative voltage regulator available in a compact and efficient 4-pin SOT-223 surface mount package. This device supports output voltages ranging from -1.2 V up to -37 V with a maximum output current of 1.5 A for the LM337 variant, making it well-suited for applications requiring reliable negative voltage regulation.
The device features a low quiescent current of 1.6 mA that aids in reducing power consumption during standby modes. It operates at a maximum temperature of 125°C, ensuring stability and longevity under demanding thermal conditions.
This voltage regulator offers excellent ripple rejection performance of 77 to 80 dB, which helps in filtering out AC ripple in the output supply, thereby supporting sensitive analog and mixed-signal circuits. The minimal external components required include only two resistors for voltage adjustment and a capacitor for frequency compensation, simplifying the external circuitry and saving PCB space.
The LM337IMP/NOPB is designed specifically for negative voltage regulation, making it ideal in circuits where negative bias or rail voltages are necessary. Its small and standard SOT-223 footprint suits high-density surface mount applications, including power management ICs for industrial, electronic component manufacturing, and laboratory instruments.
Adjustable output voltage from -1.2 V to -37 V. Output current capacity up to 1.5 A (LM337), 0.1 A (LM337L). Low quiescent current of 1.6 mA enhances energy efficiency. Compact SOT-223 4-pin surface mount device. Maximum operating temperature rating of 125°C.
Typical ripple rejection of 77 - 80 dB for cleaner output. Minimal external components simplify circuit design. Designed for negative polarity voltage regulation. Ideal for use in electronic components, power management circuits, and industrial equipment.
