The ADP1715/ADP1716 is a 500 mA low dropout CMOS linear regulator with a wide input voltage range and low shutdown current. It offers multiple fixed output voltage options and an adjustable output voltage option. The regulator provides excellent load/line transient response, current limit and thermal overload protection, and can be controlled with logic enable. It is suitable for applications such as notebook computers, memory components, telecommunications equipment, network equipment, DSP/FPGA/μP supplies, and instrumentation.
The ADP1715 and ADP1716 are low‑dropout, CMOS linear regulators that operate from 2.5 V to 5.5 V and deliver up to 500 mA of output current. They are offered in an 8‑lead thermally enhanced MSOP package and feature soft‑start, current‑limit, thermal‑overload protection, and an enable pin.
Typical applications include notebook computers, memory components, telecommunications equipment, network gear, and DSP/FPGA power supplies. The device provides excellent line and load transient response with only a 2.2 µF ceramic output capacitor.
