The ADR291FRZ and ADR291ERZ offer 2.5 V outputs with tighter tolerance and lower noise (8 µVp-p) but only 5 mA output current. None of these are pin-compatible drop-in replacements — the REF193GSZ is a 3 V part with 30 mA drive, so the choice depends on the required output voltage and load current. For a 3 V rail at moderate load, the REF193GSZ is the direct fit.","metaTitle":"REF193GSZ Voltage Reference, 3V Fixed, 30 mA, 8-SOIC","metaDescription":"REF193GSZ series voltage reference from Analog Devices: 3V fixed output, ±0.33% tolerance, 30 mA output, 45 µA supply, 25 ppm/°C drift, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"REF19","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"REF19","Package":"Tube","Tolerance":"±0.33%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Reference Type":"Series","Voltage - Input":"3.3V ~ 15V","lifecycle_stage":"eol_hot","Current - Output":"30 mA","Current - Supply":"45µA","Noise - 0.1Hz to 10Hz":"30µVp-p","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Temperature Coefficient":"25ppm/°C","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.98","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.98000","currency":"USD"},{"qty":10,"price":"$4.47100","currency":"USD"},{"qty":25,"price":"$4.22680","currency":"USD"},{"qty":100,"price":"$3.66330","currency":"USD"},{"qty":250,"price":"$3.47540","currency":"USD"},{"qty":500,"price":"$3.11848","currency":"USD"},{"qty":1000,"price":"$2.63004","currency":"USD"},{"qty":2500,"price":"$2.49854","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/REF19XSERIES.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is a compatible replacement for REF193GSZ?","answer":"There is no direct pin-compatible replacement from the listed peers.
