RT9193-25GB-MS

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

RT9193-25GB-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, with an input voltage range of 1.2 V to 6 V and an absolute maximum rating of 6 V.
2 VSS power_in Ground pin, which is the reference for the regulator and the CE and VOUT limits.
3 CE input Enable pin: the output is on when CE is at or above 1.6 V and off when CE is at or below 0.5 V, with an input current of 0.5 uA maximum.
4 NC unconnected No connection; the datasheet marks this pin as empty (空).
5 VOUT power_out Regulated output pin, rated up to 300 mA at VIN = 4.3 V, with an absolute maximum range of Vss-0.3 V to Vin+0.3 V.
