The 63 dB PSRR at 1 kHz makes it a candidate for post-switcher clean-up in analog or RF supply rails where ripple rejection matters. Dropout voltage is 0.22 V max at 50 mA, so the input rail can sit as low as 4.02 V and still maintain regulation — useful in battery-powered designs where the cell voltage decays. The low Iq suits always-on or sleep-mode loads where every microamp is budgeted. ## Industrial temperature range and protection Built-in protection includes overcurrent, overtemperature, and short-circuit shutdown — no external watchdog needed for basic fault containment. An Enable pin (active-high logic) allows the regulator to be gated by a GPIO or power-good signal, dropping the output to zero and reducing quiescent draw to near-zero in shutdown. ## SOT-23-5 package and footprint Housed in a 5-pin SOT-23 (SC-74A / SOT-753), the LP2980AIM5-3.8/NOPB is a surface-mount device.","metaTitle":"LP2980AIM5-3.8/NOPB LDO Regulator, 3.8V Fixed, 50mA","metaDescription":"Texas Instruments LP2980AIM5-3.8/NOPB is a 50mA fixed-output LDO with 63dB PSRR at 1kHz, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","PSRR":"63dB (1kHz)","Series":"-","Package":"Tape & Reel (TR)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"50mA","Base Product Number":"LP2980","Protection Features":"Over Current, Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~125°C","Voltage - Input (Max)":"16V","Voltage Dropout (Max)":"0.22V @ 50mA","Current - Supply (Max)":"1.2 mA","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-23-5","Current - Quiescent (Iq)":"95 µA","Voltage - Output (Min/Fixed)":"3.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/865be670b7e185d590e6565808fed4d6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AIM5-3.8%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LP2980AIM5-3.8/NOPB?","answer":"This part is obsolete and not stocked by the manufacturer.
