MIC5205-5.0YM5-TR

Microchip · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

MIC5205-5.0YM5-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 Supply Input. Operating range +2.5 V to +16 V (absolute max -20 V to +20 V). A 1 uF capacitor from IN to GND is recommended if more than 10 inches of wire separates the input from the AC filter capacitor, or if a battery is used as the input.
2 GND power_in Ground return. Ground pin current is the regulator quiescent current plus pass transistor base current (typ 1300 uA at IL = 150 mA).
3 EN input Enable/Shutdown (Input). CMOS/TTL-compatible input; logic-high (>= 2.0 V) enables the regulator, logic-low (<= 0.4 V) or open shuts it down. Operating VEN range 0 V to VIN (absolute max -20 V to +20 V). May be tied directly to IN (pin 1) if the shutdown feature is not needed.
4 BYP passive Reference Bypass. Connect an external 470 pF capacitor from BYP to GND to quiet the internal bandgap reference and significantly reduce output noise (typ 260 nV/sqrt(Hz)). May be left open if low-noise operation is not required; when used, COUT >= 2.2 uF is recommended for stability.
5 OUT power_out Regulator Output. Fixed 5.0 V on this -5.0YM5 option, guaranteed 150 mA output current. Requires COUT >= 1 uF (basic) or >= 2.2 uF when a 470 pF CBYP is used, ESR <= ~5 ohm.

Two STEP files. Same geometry, different body top:

File Size Use it when
mic5205-5-0ym5-tr.step 85 KB You want the bare part, or you mark your own boards.
mic5205-5-0ym5-tr-etched.step 2.6 MB You want the part with MIC5205-5.0YM5-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 647 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.
