MIC5205YM5-TR from Microchip, 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 | IN | power_in | Unregulated supply input, 2.5 V to 16 V operating (absolute maximum -20 V to +20 V). Requires only a small input capacitor for stability when source impedance is high. |
| 2 | GND | power_in | Device ground return. Ground pin current is the pass-transistor base current plus quiescent current (typ. 600 uA at 100 mA load). |
| 3 | EN | input | CMOS/TTL-compatible enable/shutdown input. V_IH >= 2.0 V enables the regulator; V_IL <= 0.4 V forces shutdown (I_GND drops to ~0.01 uA). Absolute maximum -20 V to +20 V; EN may be tied directly to IN for always-on operation. |
| 4 | ADJ | input | Adjust / feedback input for the adjustable MIC5205YM5 variant. Output voltage is set by an external resistor divider from OUT to ADJ to GND: V_OUT = V_REF x (1 + R2/R1). An optional C_BYP capacitor to GND at this node reduces output noise. |
| 5 | OUT | power_out | Regulated output, 150 mA guaranteed. Requires >= 1 uF output capacitor for basic operation, or >= 2.2 uF (tantalum) with a 470 pF C_BYP for low-noise operation. Typical output noise 260 nV/sqrt(Hz). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 535 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
