UA723CD from Texas Instruments, in a SOIC-14. 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 connection. |
| 2 | CURR LIM | output | Current limiter output; limit current = 0.65 V / RSC where RSC is external sense resistor. |
| 3 | CURR SENS | input | Current sense input; 0.65 V across external sense resistor RSC at current limit threshold. |
| 4 | IN- | input | Error amplifier inverting input; maximum differential voltage ±5 V to IN+. |
| 5 | IN+ | input | Error amplifier non-inverting input; maximum voltage above VCC- is 8 V. |
| 6 | REF | output | Reference voltage output; 6.8 V to 7.5 V typical at 25°C, 15 mA maximum source current. |
| 7 | VCC- | power_in | Negative supply voltage return (ground reference). |
| 8 | NC | unconnected | No connection. |
| 9 | VZ | output | Temperature-compensated reference diode; 6.2 V nominal, 25 mA maximum sink current. |
| 10 | OUTPUT | output | Regulated output voltage, adjustable 2 V to 37 V, maximum load current 150 mA. |
| 11 | VC | input | Unregulated input voltage to series pass transistor; operating range 9.5 V to 40 V. |
| 12 | VCC+ | power_in | Positive supply voltage; operating range 9.5 V to 40 V continuous, 50 V peak. |
| 13 | FREQ COMP | input | Frequency compensation terminal; connect external capacitor to VCC- for loop stability control. |
| 14 | NC | unconnected | No connection. |
