The SC-70-5 package keeps the footprint small enough for dense boards. ## 5 µs propagation delay — fast fault response That is fast enough to catch a core voltage brownout before the processor's internal POR circuit triggers — or before a flash write corrupts data. ROHS3 compliant. The base product number is TPS3803. Sourced per RFQ — confirm the BOM quantity and target lead time at quote. Surface-mount SC-70-5 (also known as SOT-353). The 5-lead package has a 0.65 mm pitch — two-layer boards break out the pins without vias.","metaTitle":"TPS3803-01MDCKREP Supervisor IC – Active, -55°C to 125°C","metaDescription":"Texas Instruments TPS3803-01MDCKREP Simple Reset/Power-On Reset IC.

The datasheet provides the formula and typical resistor values for common rail voltages.
