The 2V typical dropout at 1A means the input rail must stay above 7V to hold regulation under full load — a standard headroom requirement for 78xx-family parts. ## Ripple rejection and thermal envelope PSRR is specified at 68 dB at 120 Hz — this is the ripple-rejection figure that matters when the regulator follows a full-wave rectifier or a switching preregulator. The operating temperature range from 0°C to 125°C covers most commercial and industrial environments; the TO-220 package with a heatsink can dissipate the thermal load of a 1.5A rail, provided the input-output differential is kept within the power-dissipation budget. ## Protection features and quiescent draw Built-in over-temperature and short-circuit protection are included on-chip — the regulator shuts down before the junction exceeds the safe limit. Quiescent current is 6 mA typical, which is negligible for most loads but worth noting in always-on or battery-backed rails where the idle draw adds up.","metaTitle":"L7805ACV-DG – STMicroelectronics 5V 1.5A Linear Regulator","metaDescription":"L7805ACV-DG – STMicroelectronics fixed 5V output, 1.5A, TO-220, active lifecycle, 68dB PSRR at 120Hz.
