RT2516GSP

Richtek Tech · Linear Voltage Regulators (LDO) · SOP-8-EP

RT2516GSP from Richtek Tech, in a SOP-8-EP. 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 NC unconnected No internal connection.
2 EN input Chip enable (active-high); pulling this pin below 0.4V turns the regulator off, and the device is enabled if the pin is left open.
3 VIN power_in Power input; for full-load regulation the input must be between (VOUT + 0.5V) and 6V, with a minimum input of 1.4V and at least 10µF ceramic capacitor placed directly at this pin.
4 NC unconnected No internal connection.
5 NC unconnected No internal connection.
6 VOUT power_out Output of the regulator, which requires a minimum of 10µF capacitor placed directly at this pin.
7 ADJ input Feedback voltage input; connecting it to VOUT sets the output to 0.5V, while external feedback resistors set the output by their ratio.
8 GND power_in Ground, which must be connected to the exposed pad and the PCB ground for maximum power dissipation.
9 GND power_in Exposed pad ground, which must be soldered to a large PCB and connected to GND for maximum power dissipation.
