LP2987AIMX-5.0 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 | N/C | unconnected | No internal connection on the LP2987; the Bypass pin function is specific to the LP2988 (noise-reduction capacitor). |
| 2 | DELAY | passive | Connect a capacitor here to set the power-on reset delay; the 2.2 µA source charges it to 1.23 V, and the maximum recommended value is 1 µF. |
| 3 | GROUND | power_in | Ground reference pin; ground pin current is typically 1 mA at 200 mA load and 200 µA at 10 mA load. |
| 4 | INPUT | power_in | Unregulated supply input, operating range 2.1 V to 16 V, requiring an input capacitor of at least 2.2 µF placed within 0.5 in of the pin. |
| 5 | ERROR | output | Open-collector error/reset flag that goes low when the output drops about 5% below nominal, and requires an external pull-up resistor. |
| 6 | SHUTDOWN | input | Shutdown input: driving it low turns the regulator off (quiescent current below 2 µA), pin limits are −0.3 V to +16 V, and it must be tied to INPUT if unused. |
| 7 | OUTPUT | power_out | Regulated 5.0 V output rated for 200 mA continuous with specified peak above 250 mA, short-circuit protected, requiring a minimum of 4.7 µF output capacitance. |
| 8 | SENSE | input | Output voltage sense input, absolute maximum rating −0.3 V to +6 V. |
