(5 Pieces) LD1085V50 — TO2203 lowdropout fixed 5.0V voltage regulators, threepin package with mounting tab. Reliable replacement parts for powersupply circuits, repairs, and custom electronics projects. Key benefits Provides a steady, regulated 5.0V output for circuits that require a stable supply voltage. Lowdropout design lets you maintain regulation with a smaller inputoutput voltage difference than standard regulators, useful for batterypowered and lowvoltage designs. TO2203 package with mounting hole enables easy PCB installation and optional heatsink mounting for higherpower applications. Sold as a set of 5 identical regulators for spare parts, small production runs, or multiplechannel power systems. What this part solves Prevents voltage fluctuations that can cause erratic behavior or damage in microcontrollers, sensors, and other 5V electronics. Reduces the need for higher input voltages and bulky power arrangements when operating near supply limits. Offers a straightforward, dropin regulator option for repairing or upgrading existing TO220 circuits. Key attributes Model: LD1085V50 (fixed 5.0V output) Package: TO2203 (three leads, metal mounting tab) Quantity: 5 pieces per pack Functionality: Linear lowdropout fixedvoltage regulator Compatibility: Standard TO220 footprint — fits PCBs and heatsink mounts designed for threeterminal TO220 regulators Physical notes: Throughhole mounting; metal tab for heat dissipation and fastening Performance and installation notes Designed to deliver a stable 5.0V output under typical operating conditions. Ensure the input voltage is above the regulator's required dropout margin to maintain regulation. For moderate to load currents, attach a heatsink to the TO220 tab and follow recommended input/output bypass capacitors for stability and transient response. Suitable as a direct replacement for circuits that specify LD1085V50 in a TO2203 package. Typical use cases Powering microcontrollers, development boards, and peripheral devices that require a regulated 5V supply in hobbyist and professional electronics. or refurbishment of consumer electronics and industrial control modules that use a TO220 5V regulator. Small multichannel power designs where several identical regulators are needed for separate rails or redundancy. Package contents Five (5) LD1085V50 regulators in TO2203 package. Each unit is a threeterminal fixed 5.0V LDO regulator ready for throughhole mounting and heatsink attachment.
