Active-high enable: VSH ≥ 0.75V enables the oscillator, VSL ≤ 0.2-0.3V shuts down the IC. Shutdown current (ISSS) typ. 0.02µA, max 0.5µA at VCE=0V. |+| 2 | LX | output | Switching node - drain of the internal N-channel power MOSFET, connected to the external inductor/Schottky-diode node of the boost converter. Absolute max LX voltage -0.3 to VDD+0.3V; peak LX current ±4A. SOT23-5 recommended load ≤1A. |+| 3 | GND | power_in | Device ground reference. Return for internal power MOSFET source, control logic and reference. |+| 4 | VDD | power_in | IC power supply pin. Operating range 2.5V ≤ VDD ≤ 6V for stable operation; start-up guaranteed from 0.9V (IOUT=1mA). Absolute maximum -0.3 to 6.5V. Bypass with 0.1µF ceramic close to pin. |+| 5 | FB | input | Feedback voltage input to the internal error amplifier. Regulated to VFB = 1.25V typ (1.225-1.275V, ±2%). Set output with external divider R1/R2 from VOUT to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MICRONE |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `ME2149FM5GM5`+- `ME2149FM5GP5`+- `ME2149FM5GS`++## CAD (KiCad official)++- Symbol: `ME2149FM5G`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MICRONE datasheet](docs/me2149fm5g-datasheet.pdf) (13 pp, sha256 `12aea13e59a159b5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
