MAX8518EUB+

The MAX8518EUB+ is a 1.425V to 3.6V input, 1A, 0.2V dropout LDO regulator in 10 pin µMAX package. It operates from input voltages as low as 1.425V and able to deliver up to 1A of continuous output current with maximum dropout voltage of only 200mV. The output voltage can be set from 0.5V to (VIN - 0.2V) and is 1.4% accurate over load and line variations. It uses a small, 1µF ceramic input capacitors and 4.7µF ceramic output capacitors to deliver 1A output current. High bandwidth provides excellent transient response and limits output voltage deviation to 45mV for 20mA to 1A load step with only 4.7µF ceramic output capacitor and voltage deviations can be reduced further by increasing output capacitor. Designed with an internal P-channel MOSFET pass transistor, the MAX8518 features low 340µA supply current during dropout conditions. It is used in servers, storage, networking, base stations, optical modules, post regulators, notebooks, PDAs and ATE.
