RFQ ListingPower Management ICs
The TLE42764DV is a low-dropout linear voltage regulator from Infineon's OPTIREG automotive family, delivering up to 400 mA output current in a compact PG-TO252-5 (DPAK-5) SMT package. Supporting both fixed 5 V (±2%) and adjustable output configurations across a 4.5–40V input range with only 250 mV dropout, this LDO combines a low 100 uA quiescent current with output current limiting, reverse polarity protection, and an enable input for system power management. AEC-Q100 qualified and rated for -40°C to +150°C junction operation, the TLE42764DV is ideal for automotive and industrial applications demanding a compact, robust voltage regulator with long-term supply through at least 2038.
