TMI3101

TMI · DC-DC Converters · SOT-23-5

TMI3101 from TMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Chip Enable Pin. Drive EN above 1.5V (V_IH) to turn on the part; drive EN below 0.3V (V_IL) to shut it down (<1µA shutdown current). Do not leave EN floating. EN leakage is typically ±0.01µA (±1.0µA max). Absolute max: V_IN+0.6V.
2 GND power_in Ground Pin. Device power/signal return. Should be tied to the (-) plates of C_IN and C_OUT with a short, direct trace for proper operation.
3 LX output Power Switch Output - switching node connecting the internal PMOS/NMOS synchronous bridge to the external inductor (typ. 1µH). Absolute max: -0.3V to V_IN+0.3V (transient -3.5V to 7.5V for <5ns). Peak current limit 1.2A; PMOS R_DSON 300mΩ, NMOS R_DSON 150mΩ.
4 VIN power_in Power Supply Input, 2.5V to 6.0V operating range (Input OVP at 6.1V, UVLO 2.3V, absolute max 7V). Must be closely decoupled to GND with a 4.7µF or greater X5R/X7R ceramic capacitor. Quiescent current 40µA typ (PWM 140µA, PFM 20µA, shutdown 0.1µA).
5 FB input Output Voltage Feedback Pin. Connects to the external resistor divider tap; the internal error amplifier regulates this node to V_FB = 0.600V (±2% at 25°C). Set V_OUT with R2 = R1 / (V_OUT/V_FB - 1); R1 ≈ 100kΩ recommended for optimal transient response. Absolute max: V_IN+0.6V.

CAD (KiCad official)

  • Symbol: TMI3101
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tmi3101-etched.step / tmi3101-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmi3101.step / tmi3101.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: TMI datasheet (None pp, sha256 9efce1b9118c4d73, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
