The LP2987/8 are fixed-output 200 mA precision LDO voltage regulators with power-ON reset delay which can be implemented using a single external capacitor.
The LP2987/LP2988 are fixed‑output 200 mA precision LDO voltage regulators offering ultra‑low dropout (180 mV at 200 mA) and programmable power‑on reset. They provide low noise (LP2988 version) and high accuracy (0.5 % “A” grade) across a wide supply range up to 16 V.
The document includes a general description, features, connection diagrams, ordering information, absolute maximum ratings, electrical characteristics, typical performance curves, application hints, physical dimensions, and a life‑support policy. It serves as a reference for designers needing detailed specifications and usage guidelines.
| Dropout Voltage | 180 mV @ 200 mA load |
|---|---|
| Output Voltage Accuracy (A grade) | 0.5 % |
| Shutdown Quiescent Current | <2 µA |
| Ground Pin Current | 1 mA @ 200 mA load |
| Maximum Supply Voltage | 16 V |
The dropout voltage is 180 mV when the regulator supplies 200 mA.
It draws less than 2 µA of quiescent current when the shutdown pin is held low.
The A‑grade version provides 0.5 % output voltage accuracy at room temperature.
The regulator can operate with an input supply up to 16 V.
