This document is the product manual of ADP3309 low dropout linear regulator. It has ±1.2% accuracy, ultralow dropout, low noise, low shutdown current, and is suitable for various application scenarios.
The ADP3309 is a precision low‑dropout (LDO) linear regulator offered in a 5‑lead SOT‑23 package. It provides a wide input range of 2.8 V to 12 V, ultra‑low dropout voltage, and very low shutdown current, making it suitable for battery‑powered and space‑constrained applications such as cellular phones, notebooks, and camcorders.
The datasheet includes detailed specifications, absolute maximum ratings, pin descriptions, typical performance graphs, and application circuits. It also provides an ordering guide with multiple fixed‑output voltage options and compliance information.
| Shutdown Current | ~1 pA |
|---|
In shutdown mode the ground current is reduced to about 1 pA.
The regulator operates with an input voltage range from 2.8 V to 12 V.
It is supplied in a 5‑lead SOT‑23 (RJ‑5) package.
