RT9193-12GB-MS

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

RT9193-12GB-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 Regulator input supply. Operating range 1.2 V to 6 V (absolute max 6 V). Requires ~10 uF ceramic input capacitor (Ci) to ground for stability.
2 VSS power_in Ground / return pin (接地端). Common ground reference for input, output, and CE.
3 CE input Chip Enable (使能端). Logic high (VCEH >= 1.6 V, up to VIN) enables the regulator; logic low (VCEL <= 0.5 V) disables it and drops supply current to ~1 uA. Input current <= 0.5 uA. Do not leave floating.
4 NC unconnected No internal connection (空). Leave floating or tie to any safe potential per board convention.
5 VOUT power_out Regulated output (输出端). Fixed 1.2 V ±2% for the -12 variant, delivering up to 300 mA (VIN=4.3 V). Requires ~10 uF ceramic output capacitor (Co) to ground; internal current limit and short-circuit protection.
