# RT9193-15GB-MS

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

RT9193-15GB-MS from MSKSEMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input supply pin; the datasheet gives an input voltage range of 1.2 V to 6 V and an absolute maximum input voltage of 6 V. |
| 2 | VSS | power_in | Ground pin; the datasheet defines the absolute maximum output voltage relative to Vss (Vss-0.3 V to Vin+0.3 V) but gives no separate electrical limit for this pin. |
| 3 | CE | input | Enable pin; the datasheet gives CE high as 1.6 V minimum up to VIN and CE low as 0 V to 0.5 V, with a CE input current of 0.5 uA, and pulling CE low turns the output off. |
| 4 | NC | unconnected | No-connect pin; the datasheet marks it as empty (NC / 空) with no electrical function stated. |
| 5 | VOUT | power_out | Regulated output pin; the absolute maximum output voltage range is Vss-0.3 V to Vin+0.3 V and the absolute maximum output current is 450 mA. |
