The SOT-223-4 surface-mount package suits moderate-power boards where board space is constrained. ## Dropout and quiescent — the headroom trade-off Maximum dropout is 1 V at the full 1 A load, meaning the input must stay at least 1 V above 15 V to maintain regulation. Quiescent current is 10 mA typical, rising to 15 mA max under heavy load — not a low-Iq part, but acceptable for loads where the 15 V rail is always drawing current. ## Protection set for rugged environments On-chip protection includes over-current, over-temperature, reverse polarity, and short-circuit. The reverse-polarity clamp is a practical safeguard for industrial supplies where the input connector can be miswired. Texas Instruments lists this exact variant as Obsolete.","metaTitle":"LM2940IMPX-15/NOPB LDO Regulator, 15V Fixed, 1A, SOT-223-4","metaDescription":"Texas Instruments LM2940IMPX-15/NOPB is a fixed 15V output LDO voltage regulator rated at 1A.
