# RT2515HGSP

**Richtek Tech** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOP-8-EP

RT2515HGSP 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; this pin is not connected inside the device. |
| 2 | EN | input | Active-high chip enable; pulling this pin below 0.4V turns the regulator off, and it is enabled if left open, so connect it to VIN if not used. |
| 3 | VIN | power_in | Input voltage; for full-load regulation it must be between (VOUT + 0.5V) and 6V with a minimum of 1.4V, and a minimum 10µF ceramic capacitor should be placed directly at this pin. |
| 4 | NC | unconnected | No internal connection; this pin is not connected inside the device. |
| 5 | NC | unconnected | No internal connection; this pin is not connected inside the device. |
| 6 | VOUT | power_out | Output voltage; a minimum of 10µF capacitor should be placed directly at this pin. |
| 7 | ADJ | input | Feedback pin; 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. |
| 9 | GND | power_in | Exposed pad (GND); it must be soldered to a large PCB and connected to GND for maximum power dissipation. |

## CAD (KiCad official)

- Symbol: `RT2515HGSP`
- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.29x3mm`
- 3D model: SOP-8-EP (KiCad packages3D, STEP)
- 3D model files: `rt2515hgsp-etched.step` / `rt2515hgsp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rt2515hgsp.step` / `rt2515hgsp.glb` are the bare package body.
