TDSEMIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
RT9193-3.3 from TDSEMIC, 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 | Supply voltage input; operating range 1.8V to 7V (absolute maximum 8V); decouple with ≥10µF ceramic capacitor. |
| 2 | VSS | power_in | Ground reference pin; connect to system ground. |
| 3 | CE | input | Chip enable input; drive high (V_CEH ≥0.5V typ) to enable regulator, drive low (V_CEL = 0V) to shut down; input voltage range 0V to VIN; quiescent current 25µA typ when enabled. |
| 4 | NC | unconnected | No internal connection; leave unconnected. |
| 5 | VOUT | power_out | Regulated fixed 3.3V output; typical output voltage 3.300V, maximum output current 300mA; decouple with ≥10µF capacitor. |
