Product details

Fixed 13.7V rail — what it's for

The STMicroelectronics PB137ACV is a single-output positive linear regulator that delivers a fixed 13.7 V at up to 1 A. The TO-220-3 through-hole package suits point-of-load regulation on a power board or battery charger PCB.

58 dB PSRR — ripple rejection on the rectified line

The 58 dB power-supply rejection ratio at 120 Hz corresponds to the fundamental ripple from a full-wave bridge rectifier. For higher-frequency noise the PSRR rolls off; a post-filter cap or a small series inductor helps if the load is sensitive.

Frequently asked questions

What are the PB137ACV equivalent or replacement parts?

The LDFPVR from ST is a surface-mount adjustable LDO with similar 1 A capability but a different output voltage range and package. It is not a pin-for-pin replacement for the fixed 13.7 V TO-220 part. For a through-hole fixed-voltage alternative, check the ST L78 series in the same package family.
