1.425V to 3.6V Input, 2A,
0.2V Dropout LDO Regulators
Operating Region and Power Dissipation
The maximum power dissipation depends on the ther-
mal resistance of the IC package and circuit board, the
temperature difference between the die junction and
ambient air, and the rate of airflow. The power dissipat-
ed in the device is P = I OUT x (V IN - V 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 PC board.
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.
Applications Information
Capacitor Selection and
Regulator Stability
Capacitors are required at the MAX8526/MAX8527/
MAX8528 inputs and outputs for stable operation over
the full temperature range and with load currents up to
2A. Connect a 2.2μF capacitor between IN and ground
and a 10μF capacitor with low equivalent-series-resis-
tance (ESR) capacitor between OUT and ground for 2A
output current. The input capacitor (C IN ) lowers the
source impedance of the input supply. If input-supply
source impedance is high, place a larger input capaci-
tor close to IN to prevent V IN sagging due to load tran-
sients. Smaller output capacitors can be used for output
currents less than 2A. Calculate C OUT as follows:
C OUT = I OUT(max) (1μF / 200mA)
Noise, PSRR, and Transient Response
The MAX8526/MAX8527/MAX8528 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 MAX8526/
MAX8527/MAX8528 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 2A is
45mV. Use larger output ceramic capacitors greater
than 10μF up to 100μF to attenuate the overshoot.
