No crystal, ceramic resonator, or external timing capacitor is needed — the frequency is programmed by the resistor value between the SET pin and ground. Supply current is 700 µA typical across the full frequency range, making it a low-power alternative to crystal oscillators in battery-operated or power-sensitive designs. The 2.7V to 5.5V supply range lets it run directly from a 3.3V or 5V rail without a separate LDO. ## Active production — no end-of-life concern The part is ROHS3 compliant and available in Tape & Reel (TR) or Cut Tape (CT) packaging. ## TSOT-23-5 footprint — layout checklist Package is the 5-lead Thin SOT-23 (TSOT-23-5), supplier device package TSOT-23-5. No exposed pad — thermal relief is through the leads only. A bypass capacitor at the V+ pin within 5 mm of the package is sufficient for decoupling.","metaTitle":"LTC1799CS5#TRMPBF Silicon Oscillator 1kHz-33MHz TSOT-23-5","metaDescription":"Analog Devices LTC1799CS5#TRMPBF programmable silicon oscillator, 1kHz to 33MHz, 700µA supply, 2.7V-5.5V, SOT-23-5 Thin, Active.

The relationship is fO = 10 MHz × (10 kΩ / RSET). For example, a 10 kΩ resistor gives 10 MHz; a 100 kΩ resistor gives 1 MHz. The resistor value should be between 3.3 kΩ and 1 MΩ to stay within the 1 kHz to 33 MHz range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC1799CS5TRMPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC1799CS5TRMPBF when reusing this data.
