MIC5205-3.3YM5-MS

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

MIC5205-3.3YM5-MS from MSKSEMI, 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 VIN power_in Unregulated input supply. Operating range 3.0 V to 24 V (absolute max -0.3 V to +26 V). Decouple with a >=1 uF ceramic capacitor placed close to the pin.
2 VSS power_in Device ground / return for the internal reference, error amplifier, and pass FET. Connect to the system ground plane.
3 CE input Chip Enable (active high). Drive >=1.7 V (up to 24 V) to enable the regulator; drive <=0.3 V (or tie to VSS) to place the device in shutdown (ISTANDBY <=0.2 uA), during which VOUT is actively discharged through ~300 Ω. Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to VSS for board layout convenience.
5 VOUT power_out Regulated 3.3 V output (±2%), rated 150 mA (typ 350 mA capability, 400 mA short-circuit limit). Requires a >=1 uF ceramic output capacitor to ground for stability; dropout is ~200 mV at 100 mA.
