IC REG LIN NEG ADJ 1.5A TO220Manufacturer: onsemi
Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The onsemi LM337BT is a negative adjustable linear voltage regulator. This component is designed to deliver a stable output voltage from a negative input supply, with an output current capability of up to 1.5A. The output voltage is adjustable via external resistors, with a minimum fixed output of -1.2V and a maximum adjustable output of -37V. Key protection features include over-current and over-temperature shutdown. The device exhibits a typical Power Supply Rejection Ratio (PSRR) of 77dB at 120Hz. This through-hole mounted TO-220-3 package is suitable for a wide operating temperature range of -40°C to 125°C. The LM337BT is commonly utilized in power supply circuits for telecommunications, industrial control, and automotive applications requiring precise negative voltage regulation.
