It delivers up to 200 mA from a positive input between 2.3 V and 16.5 V, with the output adjustable down to -12 V or fixed at -1.31 V. The part is in an 8-SOIC package and rated for 0°C to 70°C ambient, so it's a commercial-temperature part; don't expect it to hold regulation in an unheated enclosure. ## Output voltage range — what you can actually get The output can be set anywhere from -1.31 V down to -12 V, depending on the feedback resistor divider. The fixed -1.31 V option is useful if you just need a small negative bias for an op-amp or a charge-pump reference. The -12 V ceiling is the practical limit for a 16.5 V input rail; if you need a deeper negative rail, this isn't the part. ## Lifecycle and sourcing reality The MAX636ACSA+ is listed as Active with ROHS3 compliance. No last-time-buy notice, no NRND flag. That means you can still design it into a new BOM without worrying about an imminent EOL.","metaTitle":"Maxim Integrated MAX636ACSA+ Buck Regulator, 200 mA, 50 kHz","metaDescription":"MAX636ACSA+ is an active buck regulator from Maxim Integrated. 200 mA output, 50 kHz switching, adjustable down to -12 V. 8-SOIC, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Function":"Step-Down/Inverted","Topology":"Buck","Output Type":"Adjustable (Fixed)","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Output":"200mA","Number of Outputs":"1","Output Configuration":"Negative","Frequency - Switching":"50kHz","Operating Temperature":"0°C ~ 70°C (TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"16.5V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"-12V","Supplier Device Package":"8-SOIC","Voltage - Output (Min/Fixed)":"-1.31V (-12V)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.68","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.68000","currency":"USD"},{"qty":10,"price":"$6.03700","currency":"USD"},{"qty":25,"price":"$5.75600","currency":"USD"},{"qty":100,"price":"$4.99790","currency":"USD"},{"qty":250,"price":"$4.77328","currency":"USD"},{"qty":500,"price":"$4.35208","currency":"USD"},{"qty":1000,"price":"$3.79053","currency":"USD"},{"qty":2500,"price":"$3.65014","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/722c1b5dab6e276a6ebbcfdede371437.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can MAX636ACSA+ be used for negative voltage regulation?","answer":"Yes, the MAX636ACSA+ is designed for an inverted topology and can generate a regulated negative output from a positive input rail.
