It is a workhorse part for generating a clean +5 V rail from a higher unregulated DC input, typical in industrial control boards, motor-drive auxiliary supplies, and test equipment where a switching regulator's ripple is unacceptable. With a maximum input voltage of 35 V and a dropout voltage of 2 V typ at 1 A load, the input rail must stay above 7 V to maintain regulation under full load. The 68 dB PSRR at 120 Hz provides solid line-frequency ripple rejection, important for analog front-end supplies. ## Dropout and thermal headroom The 2 V dropout at 1 A is typical for a standard NPN-pass linear regulator. The LDFPVR adjustable LDO offers 1 A output with 62 dB PSRR at 120 Hz, but its 16 V max input and adjustable output suit a different design target.","metaTitle":"L7805ABV-DG STMicro 5V 1.5A TO-220 Linear Regulator","metaDescription":"STMicroelectronics L7805ABV-DG, 5V fixed output, 1.5A, TO-220, active production. 68dB PSRR at 120Hz, -40°C to 125°C.
