H8118A45M5R from Shanghai Siproin Microelectronics, 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 | EN | input | Shutdown pin: H level gives normal operation and L level stops the step-up; the shutdown input voltage is VSH min 0.75 V and VSL max 0.3 V, with absolute maximum EN pin voltage VSS-0.3 to VSS+8 V. |
| 2 | VOUT | power_out | Output voltage pin; absolute maximum VOUT pin voltage is VSS-0.3 to VSS+8 V. |
| 3 | NC | unconnected | No connection (N.C.). |
| 4 | GND | power_in | GND pin. |
| 5 | LX | output | External inductor connection pin; absolute maximum LX pin voltage is VSS-0.3 to VSS+8 V and LX pin current is 1000 mA. |
