Input voltage max is 10V. ## Industrial temperature grade — rated for the harsh environments Over-temperature protection is built in, so a momentary overload or high ambient triggers a safe shutdown rather than silicon damage. No reverse-current or short-circuit protection is listed — the load side should be reviewed for fault conditions that could pull the output below ground. ## Sourcing and lifecycle This is a standard-catalog part suitable for both new-design BOMs and production replenishment. RoHS compliance is listed as non-compliant. Verify date-code and Pb-free finish options before committing the BOM.","metaTitle":"LP38690SD-2.5 LDO Regulator, Fixed 2.5V, 1A, 6-WSON","metaDescription":"LP38690SD-2.5 fixed 2.5V LDO regulator, 1A output, 55dB PSRR at 120Hz, 55µA Iq, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"55dB (120Hz)","Package":"Bulk","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"1A","Protection Features":"Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"10V","Voltage Dropout (Max)":"1.3V @ 1A","Current - Supply (Max)":"100 µA","Supplier Device Package":"6-WSON (3x3)","Current - Quiescent (Iq)":"55 µA","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.72","stockQuantity":0,"priceTiers":[{"qty":419,"price":"$0.72000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/07172954fd62d719c228ed3755712fa8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the LP38690SD-2.5 require external capacitors?","answer":"The datasheet for this LDO family specifies input and output capacitors for stability — typically a 1 µF ceramic on the input and a 10 µF ceramic on the output. The evidence does not carry the exact values, so follow the manufacturer's recommended capacitor types and ESR ranges from the LP38690 datasheet for stable operation at 1A."},{"question":"What is the PSRR of the LP38690SD-2.5?","answer":"The power-supply rejection ratio is 55 dB at 120 Hz.
