Quiescent current is 100 µA. PSRR is 55 dB at 120 Hz. ## Package and mounting — TO-252 with tab The TO-252-3 (DPak) surface-mount package has two leads plus a tab that is the thermal path. The tab is electrically connected to the output pin. ## Lifecycle and sourcing The LP38691DT-2.5 carries an active lifecycle status, so there is no last-time-buy clock running. It is RoHS non-compliant per the listing — verify your assembly line's exemption allowance if you are building for a restricted-material jurisdiction.","metaTitle":"LP38691DT-2.5 LDO Regulator, 2.5V Fixed Output, 500mA","metaDescription":"LP38691DT-2.5 fixed 2.5V LDO, 500mA output, 0.725V dropout max, 100µA Iq, 55dB PSRR at 120Hz, -40°C to 125°C, active production.","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":"TO-252-3, DPak (2 Leads + Tab), SC-63","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"500mA","Protection Features":"Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Input (Max)":"10V","Voltage Dropout (Max)":"0.725V @ 500mA","Supplier Device Package":"TO-252","Current - Quiescent (Iq)":"100 µA","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.79","stockQuantity":0,"priceTiers":[{"qty":380,"price":"$0.79000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e3c30fa79ef6e17bc54c3de5a2dd84b2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is LP38691DT-2.5's PSRR?","answer":"PSRR is 55 dB at 120 Hz — that attenuates 120 Hz ripple from a full-wave rectifier by about 560 times.
