It accepts an input from 1.8V to 10V and delivers a regulated 5V output at up to 750mA switch current, switching at 155kHz. The 1.8V minimum input voltage means this regulator can start up and deliver 5V from a pair of nearly-depleted alkaline batteries (down to 0.9V each) or from a single lithium-ion cell through most of its discharge curve. The 10V maximum input gives headroom for 5V or 9V wall-wart supplies without a pre-regulator. For a battery-powered product that needs a 5V rail for sensors, a microcontroller, or a display, the LT1303CN8-5#PBF handles the boost stage with a single inductor and a Schottky diode — no external switch transistor needed. ## Active production and ROHS3 — no EOL concern for new builds The ROHS3 compliance covers the full substance restriction list, so it passes environmental review for EU and global markets without an exemption chase. For a production run or a repair stock order, the active lifecycle status means the supply channel is the standard distribution network — not a broker-only scavenger hunt. The through-hole DIP package is a mature form factor with consistent supply from multiple stocking locations.","metaTitle":"LT1303CN8-5#PBF Boost Converter, Fixed 5V, 750mA, 8-DIP","metaDescription":"Linear Technology LT1303CN8-5#PBF step-up DC-DC converter.

The key difference is packaging: the LT1305CS8#PBF is a surface-mount SOIC-8, not a through-hole DIP. It also has a higher 2.5A switch current rating. The LT1303CN8-5#PBF will not drop into a board laid out for the surface-mount LT1305CS8#PBF without a PCB redesign."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT1303CN8-5PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT1303CN8-5PBF when reusing this data.
