The 0.3 V maximum dropout at full load tells you the minimum input headroom: a 5.3 V rail (or a 5 V rail with a diode drop) keeps the output in regulation. ## Dropout and input range — headroom planning Maximum input voltage is 26 V, so this part can regulate down from a 24 V industrial bus or an unregulated 12 V battery rail. The 15 mA quiescent current is not ultra-low for a battery application, but the 0.3 V dropout at 100 mA means you can run it from a 5.3 V post-switcher with less than 0.3 V of headroom loss. Quiescent current rises to 30 mA max under heavy load — budget that into the thermal calculation for the 8-SOIC package. ## Protection features and temperature grade Built-in over-temperature, reverse polarity, and short-circuit protection reduce external component count. Reverse polarity protection alone saves a series Schottky diode on the input — a real BOM saving in automotive or industrial 24 V designs where a reverse-battery event is a field failure.","metaTitle":"LM2931AM-5.0/NOPB LDO Regulator, 5V Fixed, 100mA, 80dB PSRR","metaDescription":"Texas Instruments LM2931AM-5.0/NOPB positive fixed LDO, 5V output, 100mA, 0.3V dropout max, 80dB PSRR at 120Hz.
