LP2988IMX-5.0

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

LP2988IMX-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 BYPASS passive A low-leakage bypass capacitor (NPO/COG ceramic or film recommended) connects here to reduce output noise, and any leakage shifts the regulated output voltage. Bypass pin ESD rating is 500V (LP2988 only).
2 DELAY passive A single external capacitor sets the power-on reset delay, charged by a 2.2 µA source, with a maximum recommended value of 1 µF and no aluminum electrolytics; the Delay pin is ESD rated at 1.5kV.
3 GROUND power_in Ground return pin for the regulator.
4 INPUT power_in Unregulated supply input with an operating range of 2.1V to +16V (survival −0.3V to +16V), requiring an input capacitor of at least 2.2 µF located within 0.5 inch 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; its absolute maximum voltage is −0.3V to +16V.
6 SHUTDOWN input Driving this pin low turns the regulator off and driving it high turns it on, with a slew rate of at least 40 mV/µs required and an absolute maximum of −0.3V to +16V; tie it to INPUT if the feature is not used.
7 OUTPUT power_out Regulated 5.0V output rated for 200 mA continuous and more than 250 mA peak, requiring a minimum of 4.7 µF output capacitance with ESR within the stable range and an absolute maximum of −0.3V to +16V.
8 SENSE input Sense input for the output voltage feedback, rated −0.3V to +6V absolute maximum.
