The LM2930S-5.0/NOPB is a fixed-output positive low-dropout voltage regulator manufactured by Texas Instruments. It provides a stable 5V output with a maximum current capacity of 1A. The device operates within an input voltage range up to 10V and features a typical dropout voltage of 450mV at full load. Designed for surface-mount applications, it utilizes the TO-263 (D2PAK) package. Key electrical specifications include a quiescent current of 10mA and a line regulation of 50mV. It supports operation temperatures from -40°C to +125°C and includes internal protections against overcurrent and thermal overload.
Verify the exact suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer documentation. Confirm the package type matches the required PCB footprint, specifically the TO-263 variant. Ensure input voltage does not exceed the absolute maximum rating of 10V to prevent device damage. Check for moisture sensitivity level requirements during storage and handling procedures.
Select this component when a fixed 5V rail is needed with high current drive in a compact surface-mount form factor. It is suitable for applications where input voltage is close to the output voltage due to its low dropout characteristic. Consider thermal dissipation requirements given the 1A output capability in the D2PAK package. Compare against adjustable regulators if variable output is required later.
This part belongs to the LM2930 series of three-terminal positive regulators. It is functionally similar to the LM7805 but offers superior dropout performance. The 'S' designation indicates the surface-mount TO-263 package. The '/NOPB' suffix denotes a non-phosphorus bromide lead-free finish compliant with environmental standards.
LM2930CT-5.0/NOPB: Through-hole TO-220 equivalent. LM2930S-5.0: Older version without NOPB suffix. UA7805CKTTR: Alternative 7805-style regulator.
