Quiescent current is 120 µA typical, which keeps the self-heating low in the TO-92-3 package — no heatsink needed for most loads, as long as the input-to-output differential stays under a few volts. Input voltage can go up to 30 V absolute maximum, so the part tolerates unregulated supplies or battery voltages well above the 5 V rail. Protection features include over-current and over-temperature shutdown, which guard against output shorts or thermal runaway in confined enclosures. The TO-92-3 package is not board-space-efficient, but it is easy to hand-solder and replace in field repairs. ## Sourcing posture — active and available No official second-source or pin-compatible replacement is listed, but the LP2950 family includes other fixed-voltage variants (3.0 V, 3.3 V, adjustable) in the same TO-92-3 footprint if the design needs a different rail.","metaTitle":"LP2950ACZ-5.0/NOPB Fixed 5V LDO Regulator, 100mA, TO-92-3","metaDescription":"Texas Instruments LP2950ACZ-5.0/NOPB is a fixed 5V positive LDO voltage regulator rated for 100mA output.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"-","Series":"-","Package":"Bulk","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"100mA","Base Product Number":"LP2950","Protection Features":"Over Current, Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~125°C","Voltage - Input (Max)":"30V","Voltage Dropout (Max)":"0.6V @ 100mA","Current - Supply (Max)":"14 mA","Voltage - Output (Max)":"-","Supplier Device Package":"TO-92-3","Current - Quiescent (Iq)":"120 µA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/caf18a64c65ed1aae14f4e93b3409731.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2950ACZ-5.0%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Does LP2950ACZ-5.0/NOPB need a heat sink?","answer":"For most applications with input-to-output differential under a few volts and load under 100 mA, the TO-92-3 package dissipates the heat without a heatsink.
