General Description
Features
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
current with a maximum dropout voltage of only 200mV.

and is 1.4% accurate over load and line variations, from
0°C to +85°C.
These regulators use small, 1µF ceramic input capaci-
tors and 4.7µF ceramic output capacitors to deliver 1A
output current. High bandwidth provides excellent tran-
sient response and limits the output voltage deviation to
45mV for a 20mA to 1A load step, with only a 4.7µF
ceramic output capacitor, and the voltage deviations can
be reduced further by increasing the output capacitor.

Ordering Information
Designed with an internal p-channel MOSFET pass
transistor, the MAX8516/MAX8517/MAX8518 feature
low 340µA (typ) supply current during dropout condi-
tions. Soft-start reduces inrush current. Other features
include a logic-controlled shutdown mode, short-circuit
protection, and thermal-overload protection.

Output Voltage Selection
Detailed Description
The MAX8516/MAX8517/MAX8518 feature an
adjustable output voltage from 0.5V to 3.4V, using two
external resistors connected as a voltage-divider to FB
as shown in Figure 1. The output voltage is set by the
following equation:
The MAX8516/MAX8517/MAX8518 are low-input, low-
dropout, PMOS regulators capable of delivering up to
1A of output current with as little as 200mV of headroom
from input to output. The PMOS output stage can be dri-
ven from input voltages down to +1.425V without sacri-
ficing stability or transient performance. Since these
regulators have a PMOS output device, supply current
is not a significant function of load or input headroom.

Internal p-Channel Pass Transistor
The MAX8516/MAX8517/MAX8518 feature a 100mΩ (typ)
p-channel MOSFET pass transistor. Unlike similar
designs using pnp pass transistors, p-channel MOSFETs
require no base drive, which reduces quiescent current.
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.

Short-Circuit/Thermal Fault Protection
The MAX8516/MAX8517/MAX8518 are fully protected
from a short circuit at the output through current-limiting
and thermal-overload circuitry. In the fault condition
when the output is shorted to ground, the output current
is limited to 2A. Under these conditions, the part quickly
heats up. When the junction temperature reaches
+165°C, the thermal-overload circuitry turns off the
output, allowing the part to cool down. When the junction
temperature cools to +150°C, the output turns back on
and tries to reestablish regulation. Current limiting and
thermal protection continue until the fault is removed. For
continuous operation, do not exceed the absolute maxi-

Shutdown Mode
The MAX8516/MAX8517/MAX8518 include an enable

normal operation, connect the EN to IN. During shut-
down, an internal 10kΩ resistor pulls down the output.
Power-OK (MAX8517 Only)
The MAX8517 features a power-OK (POK) output to
indicate the status of the output. POK remains high
when the regulator output is within 10% of its nominal
output voltage. If the output voltage falls or rises out-
side this range, POK transitions low. This open-drain
output requires an external pullup resistor to IN. An
internal delay circuit prevents POK from switching for
50µs (typ) after the trip threshold is initially reached. If
the part is in shutdown mode, POK is low.

put requires an external pullup resistor to IN. If the part

The maximum power dissipation depends on the ther-

temperature difference between the die junction and
ambient air, and the rate of airflow. The power dissipat-
Noise, PSRR, and Transient Response
The MAX8516/MAX8517/MAX8518 are designed to
operate with low dropout voltages and low quiescent
currents while still maintaining good noise, transient
response, and AC rejection (see the Typical Operating
Characteristics for a plot of Power-Supply Rejection
Ratio (PSRR) vs. Frequency). When operating from
noisy sources, improved supply-noise rejection and
transient response can be achieved by increasing the
values of the input and output bypass capacitors and
through passive filtering techniques. The MAX8516/
MAX8517/MAX8518 load-transient response graphs
(see the Typical Operating Characteristics) show two
components of the output response: a DC shift from the
output impedance due to the load current change, and
the transient response. A typical transient overshoot for
a step change in the load current from 20mA to 1A is
45mV. Use larger output ceramic capacitors greater
than 4.7µF up to 50µF to attenuate the overshoot.

).
OUT
OUT
The package features an exposed thermal pad on its
underside. This pad lowers the thermal resistance of
the package by providing a direct heat conduction
path from the die to the PCB.
Additionally, the ground pins (GND) perform the dual
function of providing an electrical connection to system
ground and channeling heat away. Connect the
exposed backside pad and GND to the system ground
using a large pad or ground plane, or multiple vias to
the ground plane layer.

high, place a larger input capacitor close to IN to prevent
V
sagging due to load transients. Smaller output capac-
IN
itors can be used for output currents less than 1A.
Calculate C
