Linear voltage regulators (LDOs) provide clean, low-noise DC output for sensitive analog circuits, RF front-ends, and microcontroller power rails where switching regulator noise is unacceptable. Our inventory includes fixed and adjustable LDOs in SOT-23, SOT-223, TO-92, TO-220, and DPAK packages from Texas Instruments (TPS7A series), ON Semiconductor (NCP117), STMicroelectronics (LD1117/L78xx), Microchip (MCP1700), and Diodes Inc., covering output voltages from 1.2V to 36V and currents from 100mA to 5A. Legacy and industrial designs often depend on specific LDO part numbers with long lead times or that have been discontinued. We stock a wide range of older LDO references — including military-temp and extended-range variants — for repair, sustaining production, and prototype builds. Request a quote for volume pricing.
