The LP2985 is a 150 mA, fixed-output voltage regulator designed to provide ultra low-dropout and low noise in battery powered applications. It delivers unparalleled performance in all specifications critical to battery-powered designs using an optimized VIP® (Vertically Integrated PNP) process.
The LP2985 is a 150 mA fixed‑output voltage regulator designed for ultra‑low dropout and low noise in battery‑powered applications. It offers typical dropout of 300 mV at 150 mA, ground‑pin current as low as 850 pA, and a sleep‑mode quiescent current below 1 pA. The device is stable with output capacitor ESR as low as 5 mΩ and provides 1 % output voltage tolerance (A‑grade).\n\nAvailable in SOT‑23 and micro‑SMD packages, the LP2985 supports a range of output voltages from 2.5 V to 5.0 V. Ordering information, package dimensions, and detailed electrical characteristics are provided, along with application hints for low‑noise and low‑ESR designs.
| Dropout Voltage | Typically 300 mV @ 150 mA load |
|---|---|
| Ground Pin Current | Typically 850 pA @ 150 mA load |
| Sleep‑Mode Quiescent Current | < 1 pA when ON/OFF pin is pulled low |
| Output Voltage Tolerance | 1 % (A‑grade) |
| Stability with Low‑ESR Capacitor | Stable with ESR as low as 5 mΩ |
The LP2985 typically has a dropout voltage of 300 mV at a 150 mA load.
In sleep mode the LP2985 draws less than 1 pA of quiescent current when the ON/OFF pin is pulled low.
The device offers a 1 % output voltage tolerance (A‑grade).
The LP2985 is offered in SOT‑23 and micro‑SMD packages, including 5‑lead small outline and 5‑bump variants.
