The ADP199 is a high-side load switch designed to operate between 0.9V and 3.6V. It features low RDSON, low input voltage range, 500mA continuous operating current, 1.2V logic compatible enable input, etc.
The ADP199 is a high‑side load switch designed for operation between 0.9 V and 3.6 V. It provides power‑domain isolation, low on‑resistance (40 mΩ) and supports up to 500 mA continuous load current while drawing only a few microamps of quiescent current.
The device is offered in an ultra‑small 0.8 mm × 0.8 mm × 0.5 mm 4‑ball WLCSP package, making it suitable for mobile phones, digital cameras, portable equipment and other battery‑powered applications.
