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.","metaTitle":"STMicroelectronics PB137ACV Linear Regulator, 13.7V Fixed","metaDescription":"PB137ACV from ST: fixed 13.7V output, 1A, 2.6V dropout at 1A, 58dB PSRR at 120Hz, TO-220 through-hole.
