MAX8510/MAX8511/
MAX8512
Ultra-Low-Noise, High PSRR,
Low-Dropout, 120mA Linear Regulators
General Description
The MAX8510/MAX8511/MAX8512 ultra-low-noise, lowdropout (LDO) linear regulators are designed to deliver
up to 120mA continuous output current. These regulators
achieve a low 120mV dropout for 120mA load current.
The MAX8510 uses an advanced architecture to achieve
ultra-low output voltage noise of 11μVRMS and PSRR of
54dB at 100kHz.
The MAX8511 does not require a bypass capacitor, hence
achieving the smallest PC board area. The MAX8512’s
output voltage can be adjusted with an external divider.
The MAX8510/MAX8511 are preset to a variety of voltages in the 1.5V to 4.5V range. Designed with a P-channel
MOSFET series pass transistor, the MAX8510/MAX8511/
MAX8512 maintain very low ground current (40μA).
The regulators are designed and optimized to work with
low-value, low-cost ceramic capacitors. The MAX8510
requires only 1μF (typ) of output capacitance for stability
with any load. When disabled, current consumption drops
to below 1μA.
Package options include a 5-pin SC70 and a tiny 2mm x
2mm x 0.8mm TDFN package.

Detailed Description
The MAX8510/MAX8511/MAX8512 are ultra-low-noise,
low-dropout, low-quiescent current linear regulators
designed for space-restricted applications. The parts are
available with preset output voltages ranging from 1.5V
to 4.5V in 100mV increments. These devices can supply
loads up to 120mA. As shown in the Functional Diagram,
the MAX8510/MAX8511 consist of an innovative bandgap
core and noise bypass circuit, error amplifier, P-channel
pass transistor, and internal feedback voltage-divider. The
MAX8512 allows for adjustable output with an external
feedback network.
The 1.225V bandgap reference is connected to the error
amplifier’s inverting input. The error amplifier compares
this reference with the feedback voltage and amplifies the
difference. If the feedback voltage is lower than the reference voltage, the pass-transistor gate is pulled low. This
allows more current to pass to the output and increases
the output voltage. If the feedback voltage is too high,
the pass transistor gate is pulled high, allowing less current to pass to the output. The output voltage is fed back
through an internal resistor voltage-divider connected to
the OUT pin.
An external bypass capacitor connected to BP (MAX8510)
reduces noise at the output. Additional blocks include a
current limiter, thermal sensor, and shutdown logic.
www.maximintegrated.com
Unregulated Input Supply
Exposed Pad (TDFN Only). Internally connected to GND. Connect
to a large ground plane to maximize thermal performance. Not
intended as an electrical connection point.
Internal P-Channel Pass Transistor
The MAX8510/MAX8511/MAX8512 feature a 1Ω (typ)
P-channel MOSFET pass transistor. This provides several advantages over similar designs using a PNP pass
transistor, including longer battery life. The P-channel
MOSFET requires no base drive, which considerably
reduces quiescent current. PNP-based regulators waste
considerable current in dropout when the pass transistor
saturates. They also use high base-drive current under
heavy loads. The MAX8510/MAX8511/MAX8512 do not
suffer from these problems and consume only 40μA of
quiescent current in light load and 220μA in dropout (see
the Typical Operating Characteristics).
Output Voltage Selection
The MAX8510/MAX8511 are supplied with factory-set
output voltages from 1.5V to 4.5V, in 100mV increments
(see Ordering Information). The MAX8512 features a
user-adjustable output through an external feedback network (see the Typical Operating Circuits).
To set the output of the MAX8512, use the following equation:
VOUT
R1 = R2 X
-1
VREF
where R2 is chosen to be less than 240kΩ and VREF =
1.225V. Use 1% or better resistors.
Maxim Integrated │ 6
MAX8510/MAX8511/
MAX8512
Shutdown
The MAX8510/MAX8511/MAX8512 feature a low-power
shutdown mode that reduces quiescent current less than
1μA. Driving SHDN low disables the voltage reference,
error amplifier, gate-drive circuitry, and pass transistor
(see the Functional Diagram), and the device output
enters a high-impedance state. Connect SHDN to IN for
normal operation.
Current Limit
The MAX8510/MAX8511/MAX8512 include a current limiter, which monitors and controls the pass transistor’s gate
voltage, limiting the output current to 200mA. For design
purposes, consider the current limit to be 130mA (min) to
300mA (max). The output can be shorted to ground for an
indefinite amount of time without damaging the part.
Thermal-Overload Protection
Thermal-overload protection limits total power dissipation
in the MAX8510/MAX8511/MAX8512. When the junction
temperature exceeds TJ = +160°C, the thermal sensor
signals the shutdown logic, turning off the pass transistor and allowing the IC to cool down. The thermal sensor
turns the pass transistor on again after the IC’s junction
temperature drops by 10°C, resulting in a pulsed output
during continuous thermal-overload conditions.
Thermal-overload protection is designed to protect the
MAX8510/MAX8511/MAX8512 in the event of a fault condition. For continual operation, do not exceed the absolute maximum junction temperature rating of TJ = +150°C.
Operating Region and Power Dissipation
The MAX8510/MAX8511/MAX8512 maximum power dissipation depends on the thermal resistance of the case
and circuit board, the temperature difference between
the die junction and ambient, and the rate of airflow. The
power dissipation across the device is:
P = IOUT (VIN - VOUT)
The maximum power dissipation is:
PMAX = (TJ - TA) / (θJC + θCA)
where TJ - TA is the temperature difference between the
MAX8510/MAX8511/MAX8512 die junction and the surrounding air, θJC is the thermal resistance of the package,
and θCA is the thermal resistance through the PC board,
copper traces, and other materials to the surrounding air.
The GND pin of the MAX8510/MAX8511/MAX8512 performs the dual function of providing an electrical connection to ground and channeling heat away. Connect the
GND pin to ground using a large pad or ground plane.

Ultra-Low-Noise, High PSRR,
Low-Dropout, 120mA Linear Regulators
Noise Reduction
For the MAX8510, an external 0.01μF bypass capacitor between BP and OUT with innovative noise bypass
scheme reduces output noises dramatically, exhibiting
11μVRMS of output voltage noise with CBP = 0.01μF and
COUT = 1μF. Startup time is minimized by a poweron circuit that precharges the bypass capacitor.
Applications Information
Capacitor Selection
and Regulator Stability
Use a 1μF capacitor on the MAX8510/MAX8511/MAX8512
input and a 1μF capacitor on the output. Larger input
capacitor values and lower ESRs provide better noise
rejection and line-transient response. Reduce output
noise and improve load-transient response, stability, and
power-supply rejection by using large output capacitors.
Note that some ceramic dielectrics exhibit large capacitance and ESR variation with temperature. With dielectrics such as Z5U and Y5V, it may be necessary to use
a 2.2μF or larger output capacitor to ensure stability at
temperatures below -10°C. With X7R or X5R dielectrics,
1μF is sufficient at all operating temperatures. A graph of
the region of stable COUT ESR vs. load current is shown
in the Typical Operating Characteristics.
Use a 0.01μF bypass capacitor at BP (MAX8510) for lowoutput voltage noise. The leakage current going into the
BP pin should be less than 10nA. Increasing the capacitance slightly decreases the output noise. Values above
0.1μF and below 0.001μF are not recommended.
Noise, PSRR, and Transient Response
The MAX8510/MAX8511/MAX8512 are designed to deliver ultra-low noise and high PSRR, as well as low dropout
and low quiescent currents in battery-powered systems.
The MAX8510 power-supply rejection is 78dB at 1kHz
and 54dB at 100kHz. The MAX8511/MAX8512 PSRR
is 72dB at 1kHz and 46dB at 100kHz (see the PowerSupply Rejection Ratio vs. Frequency graph in the Typical
Operating Characteristics).
When operating from sources other than batteries,
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 Typical Operating Characteristics
show the MAX8510/MAX8511/MAX8512 line- and loadtransient responses.

Dropout Voltage
A regulator’s minimum dropout voltage determines the
lowest usable supply voltage. In battery-powered systems, this determines the useful end-of-life battery voltage. Because the MAX8510/MAX8511/MAX8512 use a
P-channel MOSFET pass transistor, their dropout voltage
is a function of drain-to-source on-resistance (RDS(ON))
multiplied by the load current (see the Typical Operating
Characteristics).
