For procurement teams managing a live BOM line, the NRND flag means the window for last-time-buy (LTB) orders may open at any point. Qualifying a pin-compatible supervisor now avoids a forced redesign later. ## SOT-23-5 footprint and automotive temperature grade Housed in a SOT-23-5 package, the TPS3820-33QDBVRQ1 mounts on a standard 5-pin footprint. This is the same qualification tier used by Tier-1 automotive suppliers for ECU and ADAS modules.","metaTitle":"TPS3820-33QDBVRQ1 Simple Reset IC, AEC-Q100, 2.93V Threshold","metaDescription":"TI TPS3820-33QDBVRQ1 Simple Reset/Power-On Reset IC.
