LM337SP ST Voltage Regulators - Linear

The LM337SP is an adjustable negative voltage regulator from STMicroelectronics, providing up to 1.5A output current with output voltage adjustable from -1.2V to -37V using two external resistors. For selection, verify input voltage down to -40V, line regulation, load regulation, reference voltage, and operating junction temperature range. Features include thermal overload protection, short-circuit protection, and safe area protection. Ideal for split-supply systems requiring symmetrical negative voltage rail (with LM317 positive counterpart), operational amplifier power supplies, industrial control systems requiring negative voltage regulation, dual-supply configurations in audio equipment, and any negative voltage linear regulation requiring up to 1.5A.
