The operating temperature range spans -40°C to 125°C, so the part is at home in industrial enclosures, outdoor telecom cabinets, and automotive cabin or under-hood environments that see extended thermal cycling. The enable pin (active-high) gives a clean on/off control for sequencing or power-save modes. ## Package and footprint Housed in a 5-pin SC-70-5 (also known as SOT-353), the TPS71733DCKT occupies minimal board area. Surface-mount assembly is straightforward; the small body suits dense multi-rail designs. The supplier device package is SC-70-5. ## Sourcing and lifecycle The TPS71733DCKT carries an active lifecycle status and is ROHS3 compliant.","metaTitle":"TPS71733DCKT LDO Regulator, 3.3V Fixed Output, 150mA","metaDescription":"TI TPS71733DCKT LDO: fixed 3.3V output, 150mA, PSRR 70dB~45dB (100Hz~1MHz), dropout 0.3V max at 150mA, -40°C to 125°C, SC-70-5.
