SSP7786

Shanghai Siproin Microelectronics · Linear Voltage Regulators (LDO) · SOP-8

SSP7786 from Shanghai Siproin Microelectronics, in a SOP-8. 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 VOT1 power_out LDO second output voltage, equal to 0.66×VOUT.
2 GND power_in Ground.
3 VOUT power_out LDO output voltage, internally set to 5V, 3.3V or 2.7V depending on the part variant, with a typical current limit of 138mA shared with VOT1.
4 VDD power_in Voltage input supply used for energy storage; connect a capacitor to GND to transfer the input energy to the LDO output stage (absolute maximum 9V, VDD_ON 7.8V typical).
5 Drain passive Internal 650V power MOSFET drain that provides energy to the later stage when the input voltage drops into the charging window; connect pins 5-8 together.
6 Drain passive Internal 650V power MOSFET drain that provides energy to the later stage when the input voltage drops into the charging window; connect pins 5-8 together.
7 Drain passive Internal 650V power MOSFET drain that provides energy to the later stage when the input voltage drops into the charging window; connect pins 5-8 together.
8 Drain passive Internal 650V power MOSFET drain that provides energy to the later stage when the input voltage drops into the charging window; connect pins 5-8 together.
