# LP2954AIM

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

LP2954AIM 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 | OUT | power_out | Regulated output voltage; this pin requires an output capacitor to maintain stability, with capacitor details in the Detailed Design Procedure. |
| 2 | SENSE | input | Output voltage sense input; the datasheet gives no voltage or current limits for this pin. |
| 3 | SHUTDOWN | input | Disables the device when asserted; the datasheet gives no threshold levels for this pin in this extract. |
| 4 | GND | power_in | Ground pin for the device. |
| 5 | ERROR | output | Error output that warns when the output voltage drops; the datasheet gives no drive type or pull-up limits for this pin in this extract. |
| 6 | 5V TAP | output | Internal resistor-divider tap; the datasheet gives no limits for this pin in this extract. |
| 7 | FEEDBACK | input | Voltage feedback input used to set the adjustable output from 1.23 V to 29 V. |
| 8 | IN | power_in | Unregulated input voltage; the absolute maximum input supply voltage is 30 V, and reverse battery protection is provided for this pin. |
