The operating temperature range of -40°C to 125°C qualifies it for industrial environments. ## Protection and control features This LDO packs a full protection suite: over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO). The enable pin allows the regulator to be gated by a system controller or power-good signal, which is useful in sequenced power-up schemes. Quiescent current is 80 µA typical, with a maximum supply current of 100 µA — low enough for battery-powered equipment that stays in active mode for extended periods. ## Sourcing and lifecycle It is ROHS3 compliant.","metaTitle":"TPS71745DSET LDO Regulator, 4.5V Fixed Output, 150mA, 6-WSON","metaDescription":"TI TPS71745DSET linear regulator: 4.5V fixed output, 150mA, PSRR 70dB~45dB (100Hz~1MHz), dropout 0.3V max at 150mA, -40°C to 125°C, 6-WSON.

The TPS71745DSET is pin-compatible and shares the same package, protection features, and PSRR profile — the only difference is the output voltage. If your design needs 4.5V instead of 3.5V, it is a drop-in swap.
