LM337D2TR4G Voltage Regulator IC | ONSEMI Semiconductor

Adjustable Negative Voltage Regulator – Up to 1.5A Output Current

The LM337D2TR4G from onsemi is a versatile, adjustable 3-terminal negative voltage regulator IC capable of supplying more than 1.5A of output current across a voltage range of –1.2V to –37V. Designed for easy implementation, it requires only two external resistors to set the desired output voltage.

Featuring built-in current limiting, thermal shutdown, and safe-area compensation, the LM337D2TR4G delivers robust and reliable performance, making it highly resistant to overload and short-circuit conditions — essentially blow-out proof.

This regulator is ideal for a wide range of applications including local on-board regulation, programmable power supplies, and precision current regulation circuits.
