Product details

The LM337LMX/NOPB: The 60 dB PSRR at 120 Hz means the output ripple from a full-wave-rectified supply is attenuated by a factor of 1000. If the unregulated input carries 1 V p-p of 120 Hz ripple, the output sees roughly 1 mV p-p — enough headroom for a 12-bit ADC reference rail or a low-noise op-amp supply without an additional LC filter stage.

Protection and temperature envelope

Built-in over-temperature and short-circuit protection let the part survive a momentary output short or a thermal overload without external clamp diodes.

No official second-source alternate is listed, but the LM337 family is widely cross-referenced — confirm pin-compatibility with the specific BOM position before substituting.
