LP2989AIMMX-5.0

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · VSSOP-8-0.65mm

LP2989AIMMX-5.0 from Texas Instruments, in a VSSOP-8-0.65mm. 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 BYPASS input Bypass capacitor input; an external 10-nF capacitor connected here reduces output noise to 18 µV (typical).
2 N/C unconnected Reserved for post-packaging factory calibration of VOUT accuracy; it must be left floating and not connected to any potential.
3 GROUND power_in Ground reference pin for the regulator.
4 INPUT input Regulator power input, specified for a 2.1 V to 16 V input voltage range.
5 OUTPUT output Regulated output voltage, rated for 500-mA continuous output current.
6 SENSE input Feedback voltage sense input; the absolute maximum rating for the SENSE pin is -0.3 V to 6 V.
7 ERROR output Error signal output that goes low when the output drops approximately 5% below nominal.
8 SHUTDOWN input Shutdown input; the device draws less than 0.8 µA quiescent current when this pin is pulled low, and shutdown must be actively terminated.
