| Package | Tape & Reel (TR); Cut Tape (CT) |
| Reset timeout | 15ms Minimum |
| Case | SC-74A, SOT-753 |
The 15ms minimum reset timeout provides enough hold time for most MCUs and DSPs to complete their reset sequence before the core starts executing code.
The SC-74A / SOT-753 package (supplier device package SOT-23-5) occupies minimal board area — about 2.9 mm x 1.6 mm — making it a fit for space-constrained designs like sensor nodes or handheld instruments.
Yes — the TPS3820-33DBVT and TPS3820-33DBVR share the same die and electrical specifications (2.93V threshold, active-low push-pull output, 15ms timeout). The difference is the packaging and reel format: the DBVT variant ships in Tape & Reel, while the DBVR variant ships in Cut Tape. Both are surface-mount in the same SOT-23-5 footprint, so they are drop-in replacements for each other on the board.
