Protection set and temperature grade
The regulator integrates over-current, over-temperature, reverse-polarity, and under-voltage lockout (UVLO) protection — the UVLO ensures the output stays off until the input is high enough for proper regulation, which prevents glitched start-up. 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.
