# LM78L15ACMX

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

LM78L15ACMX from Texas Instruments, in a SOIC-8. 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 | VOUT | power_out | Regulated output pin supplying the fixed 15 V output; place the recommended 0.1 µF output capacitor as close as possible to VOUT and GND to improve load and line transient response. |
| 2 | GND | power_in | Ground pin that must be tied to ground to set VOUT to the fixed output voltage; GND is referenced for all voltages in the datasheet. |
| 3 | GND | power_in | Ground pin that must be tied to ground to set VOUT to the fixed output voltage; GND is referenced for all voltages in the datasheet. |
| 4 | NC | unconnected | No-connect pin with no internal connection on the SOIC package. |
| 5 | NC | unconnected | No-connect pin with no internal connection on the SOIC package. |
| 6 | GND | power_in | Ground pin that must be tied to ground to set VOUT to the fixed output voltage; GND is referenced for all voltages in the datasheet. |
| 7 | GND | power_in | Ground pin that must be tied to ground to set VOUT to the fixed output voltage; GND is referenced for all voltages in the datasheet. |
| 8 | VIN | power_in | Input supply pin with recommended operating input voltage of 5.1 V to 30 V for the new-die devices; place the recommended 0.33 µF input capacitor as close as possible to VIN and GND. |
