... Rev 1; 4/04 General Description The MAX8516/MAX8517/MAX8518 low-dropout linear regulators operate from input voltages as low as 1.425V and are able to deliver continuous output current with a maximum dropout voltage of only 200mV. The output voltage can be set from 0. and is 1.4% accurate over load and line variations, from 0° ...

... PNP-based regulators also waste considerable current in dropout when the pass transistor saturates and use high base-drive currents under large loads. The MAX8516/ MAX8517/MAX8518 do not suffer from these problems and consume only 340µA (typ) of quiescent current under heavy loads, as well as in dropout ...
