EG1205 from EG Micro, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Chip power supply input for the linear voltage regulators; accepts 8V to 36V. |
| 2 | VO1 | power_out | 5V regulated output with maximum output current 100mA. |
| 3 | IO | output | Over-current protection transistor output port; outputs maximum voltage VO1+0.3V. |
| 4 | IS | input | Over-current protection transistor input port; accepts 0V to 36V for current sensing. |
| 5 | Bin | input | Power transistor base input port for driving buzzers or relays; accepts 0V to 36V. |
| 6 | GND | power_in | Chip ground reference. |
| 7 | CO | output | Power transistor collector output port; outputs maximum 36V for driving external loads. |
| 8 | VO2 | power_out | 12V regulated output with maximum output current 100mA. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
