MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
RT9193-18GB-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 operating input range of 1.2 V to 6 V, with 6 V as the absolute maximum input voltage. |
| 2 | VSS | power_in | Ground pin, the regulator's return reference, as labeled 接地端 (ground terminal) in the pin definition table. |
| 3 | CE | input | Enable pin; CE at 1.6 V or higher turns the output on and CE at 0.5 V or lower turns it off, with a CE input current of 0.5 µA maximum (typ. shutdown quiescent current 1 µA). |
| 4 | NC | unconnected | No connection; the datasheet lists this pin as empty (空) and it has no electrical function. |
| 5 | VOUT | power_out | Regulated output pin; the datasheet gives an absolute range of Vss-0.3 V to Vin+0.3 V and a maximum output current of 450 mA, with 300 mA capability at Vin = 4.3 V and Vout = 3.3 V. |
