General Description
Features
● 1.425V to 3.6V Input Voltage Range
The MAX8516/MAX8517/MAX8518 low-dropout linear
regulators operate from input voltages as low as 1.425V
and are able to deliver up to 1A of continuous output cur-
rent with a maximum dropout voltage of only 200mV. The
● Guaranteed 200mV Dropout at 1A Output Current
● ±1.4% Output Accuracy Over Load, Line, and
Temperature (0°C to +85°C), ±0.6% Initial Accuracy
output voltage can be set from 0.5V to (V - 0.2V) and

● Compatible with Ceramic Capacitors
● Fast Transient Response
is 1.4% accurate over load and line variations, from 0°C
to +85°C.
These regulators use small, 1μF ceramic input capacitors
and 4.7μF ceramic output capacitors to deliver 1A out-
put current. High bandwidth provides excellent transient
response and limits the output voltage deviation to 45mV
for a 20mA to 1A load step, with only a 4.7μF ceramic out-
put capacitor, and the voltage deviations can be reduced
further by increasing the output capacitor.
● 320μA Operating Supply Current
● <25μA Shutdown Supply Current
● Short-Circuit Protection
● Thermal-Overload Protection
● Soft-Start Limits Inrush Current
Ordering Information
Designed with an internal p-channel MOSFET pass
transistor, the MAX8516/MAX8517/MAX8518 feature low
340μA (typ) supply current during dropout conditions.
Soft-start reduces inrush current. Other features include
a logic-controlled shutdown mode, short-circuit protection,
and thermal-overload protection.
