LT1054CP from Texas Instruments, in a PDIP-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 | FB/SD | input | Feedback/shutdown pin for regulation via error amplifier or low-Iq shutdown when pulled below 0.45V threshold. |
| 2 | CAP+ | passive | Positive terminal connection for external input capacitor CIN. |
| 3 | GND | power_in | Ground reference and device substrate connection. |
| 4 | CAP- | passive | Negative terminal connection for external input capacitor CIN. |
| 5 | VOUT | output | Regulated negative output voltage with 1.1V typical loss at 100mA for 3.5V ≤ VCC ≤ 15V. |
| 6 | VREF | power_in | Internal 2.5V reference voltage output (2.25V-2.75V range) for regulator feedback with 60µA output current limit. |
| 7 | OSC | input | Oscillator control pin for switching frequency adjustment (nominal 25kHz, 15-35kHz range) or external synchronization. |
| 8 | VCC | power_in | Positive supply voltage input from 3.5V to 15V (maximum 20V for regulated circuits with VOUT ≤ 15V). |
