The output is push-pull, active low, with a minimum reset timeout of 120 ms. That means no external pull-up resistor on the reset line — a BOM simplification that matters when every passive counts on a dense board. The TLV803EA29VDBZR and TLV803ED29DBZR are functional alternatives but differ in output type and timeout — verify the reset timing and pull-up requirement before swapping.","metaTitle":"TPS3839G33DBZR — TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3839G33DBZR: Active-low push-pull supervisor, 3.08 V threshold, 120 ms timeout, -40°C to 85°C, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3839","Voltage - Threshold":"3.08V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9400","priceTiers":[{"qty":1,"price":"$0.94000","currency":"USD"},{"qty":10,"price":"$0.84100","currency":"USD"},{"qty":25,"price":"$0.79800","currency":"USD"},{"qty":100,"price":"$0.65570","currency":"USD"},{"qty":250,"price":"$0.61288","currency":"USD"},{"qty":500,"price":"$0.54162","currency":"USD"},{"qty":1000,"price":"$0.42760","currency":"USD"},{"qty":3000,"price":"$0.40339","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8db2a3e3b3bb51ea8ca211210c7cfea5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3839G33DBZR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3839G33DBZR need an external pull-up resistor?","answer":"No. The output is push-pull, so the reset line is driven high and low without an external resistor.

Both are simple reset supervisors with active-low reset, but they use open-drain outputs (require a pull-up), have different reset timeout values (130 ms and 33 ms minimum respectively), and are rated to 125°C.
