LP2987AIMX-5.0

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

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.
