ST1S12GR

STMicroelectronics · DC-DC Converters · TSOT-23-5

ST1S12GR from STMicroelectronics, in a TSOT-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 EN input Enable pin with voltage range -0.3 V to VIN + 0.3 V; device ON above 1.5 V threshold, device OFF below 0.5 V threshold, input current 1 µA maximum.
2 GND power_in System ground (0 V reference).
3 SW output Switching output pin with voltage range -0.3 V to VIN + 0.3 V, connected to external inductor in step-down topology.
4 VIN power_in Input supply pin with operating voltage range 2.5 V to 5.5 V, supporting maximum output current of 0.7 A.
5 FB/VO input Feedback voltage pin with voltage range -0.3 V to 3 V and typical feedback voltage of 600 mV, connected to external resistor divider network to set output voltage.
