Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DELAY | passive | Power-on reset delay timing capacitor connection pin for implementation of programmable reset delay using a single external capacitor. |
| 2 | INPUT | power_in | Supply voltage input pin, rated for operation from 2.1V to +16V nominal input. |
| 3 | SENSE | input | Feedback voltage sense pin for precision output voltage regulation at the regulation point. |
| 4 | GROUND | power_in | Ground connection providing the power return path and voltage reference. |
| 5 | OUTPUT | power_out | Regulated output voltage pin capable of supplying 200 mA continuous output current. |
| 6 | SHUTDOWN | input | Shutdown control input pin; logic low enables regulation, low shuts down regulator to less than 2 μA quiescent current. |
| 7 | ERROR | output | Error flag and power-on reset signal output; goes low when output drops approximately 5% below nominal or provides reset timing with external delay capacitor. |
| 8 | BYPASS | passive | Bypass capacitor connection pin for reduced output noise; exclusive feature of LP2988 low-noise version. |
