RT9193-3.3

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.
