Maxim MAX8511EXKXY-T Ultra-low-noise, high psrr, low-dropout,120ma linear regulators in sc70 Datasheet

19-2732; Rev 1; 6/04
Ultra-Low-Noise, High PSRR,
Low-Dropout,120mA Linear Regulators in SC70
Features
The MAX8510/MAX8511/MAX8512 ultra-low-noise, lowdropout (LDO) linear regulators are designed to deliver up
to 120mA continuous output current from a tiny 5-pin
SC70 plastic package. 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.
♦ Space-Saving 5-Pin SC70 Package
The MAX8510/MAX8511 are preset to a variety of voltages in the 1.5V to 4.5V range. Designed with a Pchannel MOSFET series pass transistor, the MAX8510/
MAX8511/MAX8512 maintain very low ground current
(40µA).
♦ Output Voltages: 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V,
2.85V, 3V, 3.3V, 4.5V (MAX8510/MAX8511) and
Adjustable (MAX8512)
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.
♦ Excellent Load/Line Transient

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.
Internal P-Channel Pass Transistor
The MAX8510/MAX8511/MAX8512 feature a 1Ω (typ) Pchannel 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
6
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.
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.

120mA Linear Regulators in SC70
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.
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 C BP = 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
C OUT ESR vs. load current is shown in the Typical
Operating Characteristics.
Use a 0.01µF bypass capacitor at BP (MAX8510) for
low-output 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
Power-Supply 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).
