MAXIM MAX8719

19-3495; Rev 0; 11/04
High-Voltage, Low-Power Linear Regulators for
Notebook Computers
The MAX8718/MAX8719 are micropower, 8-pin TDFN
linear regulators that supply always-on, keep-alive
power to CMOS RAM, real-time clocks (RTC), and
microcontrollers in systems with high-voltage batteries.
The circuits consist of a 100mA linear regulator and a
power-good comparator (PGOOD) with fixed-output
delay. Key features include wide input voltage range,
low-dropout voltage, and low-quiescent supply current.
Despite a miserly 25µA (max) no-load quiescent current, the MAX8718/MAX8719 have good line- and loadtransient response and excellent AC power-supply
rejection. They provide a clean fixed 5V or 3.3V output
(MAX8718), or an adjustable 1.24V to 28V output
(MAX8719), even when subjected to fast supply-voltage changes that occur during the switchover from battery to AC-adapter input power. The space-saving
TDFN package has excellent thermal characteristics
and tolerates up to 1951mW of power dissipation.
Internal foldback current limiting and thermal shutdown
protect the regulator from overload and thermal faults.
In addition to the main notebook-computer application,
these devices are useful in other low-power, high-voltage applications (4V < VIN < 28V) such as smart batteries, current control loops, telecom emergency power,
and housekeeping power for off-line supplies.
The MAX8718/MAX8719 are available in a thermally
enhanced 3mm x 3mm, 8-lead TDFN package.

Note 1: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed through correlation using standard quality control (SQC) methods.
Note 2: Pulse test at VIN = 28V, IOUT = 100mA to avoid exceeding package power-dissipation limits.
Note 3: Dropout voltage is tested by reducing the input voltage until VOUT drops to 100mV below its nominal value as measured
with VIN starting 2V above VOUT.
Note 4: Specifications to -40°C are guaranteed by design, not production tested.

Detailed Description
The MAX8718/MAX8719 low-quiescent-current linear
regulators are designed primarily for high-input-voltage
applications. The MAX8718 supplies a preselected
3.3V or 5.0V output for loads up to 100mA (Figure 1).
The MAX8719 provides an adjustable voltage from
1.24V to 28V (Figure 2). The maximum output current is
a function of the package’s maximum power dissipation
for a given temperature. A 5µA load is required to maintain output regulation.
The MAX8718’s output voltage is fed back through an
internal resistive voltage-divider connected to OUT. Set
the output voltage to either 5.0V or 3.3V with the 5/3
FB
GND
R2
Figure 2. Typical Operating Circuit of the MAX8719
pin. Select the 5V output by connecting 5/3 to OUT, or
the 3.3V output by connecting 5/3 to GND.
The MAX8719’s output is adjustable with an external
resistive voltage-divider. The typical feedback threshold is 1.24V (see the Setting the MAX8719 Output
Voltage section). See Figure 3 for the MAX8718/
MAX8719 Functional Diagram.
Shutdown
The device enters shutdown mode when SHDN is low.
In shutdown mode, the internal pnp power transistor,
control circuit, reference, and all biases turn off, reducing the supply current to below 3µA. Connect SHDN to
IN for automatic startup.

Current Limit
Output current is limited to 210mA (typ). The current
limit exceeds the 100mA (min) safe operating limit. The
output can be shorted to ground for 30 seconds without
damaging the part.
Thermal-Overload Protection
When the junction temperature exceeds TJ = +165°C,
an internal thermal sensor sends a signal to the shutdown logic, turning off the pass transistor and allowing
the IC to cool. The thermal sensor turns the pass tran8
sistor on again after the IC’s junction temperature cools
by 20°C (typ), causing the output to pulse on and off
during continuous thermal-overload conditions.
Operating Region and Power Dissipation
Maximum power dissipation depends on the thermal
resistance of the case and circuit board, the temperature difference between the die junction and ambient
air, and the rate of airflow. The device’s power dissipation is P = IOUT x (VIN - VOUT). The power dissipation at
+70°C ambient is 1951mW (see the Absolute Maximum

Ratings). The thermal resistance junction-to-case of the
TDFN package is 41°C/W, and the maximum safe junction temperature is +150°C.
The GND pin and backside pad performs the dual
function of providing an electrical connection to ground
and channeling heat away from the package. Connect
GND and the backside pad to ground using a metal
trace or ground plane. The package’s overall thermal
resistance varies inversely with the copper PC board
area attached to the part. To achieve rated thermal
resistance, a copper region of at least 650mm2 should
be attached to the MAX8718/MAX8719s’ case.
Applications Information
Setting the MAX8719’s Output Voltage
Set the MAX8719’s output voltage with a resistive voltage-divider (R1 and R2 in Figure 3). Choose R2 =
125kΩ or less to maintain a 10µA minimum load on
OUT. Calculate R1 using the following equation:
⎛V
⎞
R1 = R2 × ⎜ OUT − 1⎟
⎝ VFB
⎠
where VFB = 1.24V (typ).
Capacitor Selection
Use a 0.1µF (min) capacitor on the input. Higher values
improve the line-transient response.
Use a 1µF (min) capacitor on the output, or a 15µF
capacitor for the full 100mA load current. Otherwise, use
a 1µF plus 0.16µF/mA (0.23µF/mA for the MAX8719). For
output voltages less than 3.3V, use 15µF instead of
10µF. The output capacitor’s equivalent series resistance (ESR) must be less than 1Ω for stable operation.
Output-Voltage Noise
The MAX8718/MAX8719 typically exhibit 5mV P-P of
noise during normal operation. This is negligible in
Transient Response
The Typical Operating Characteristics show the
MAX8718/MAX8719s’ load-transient response. When a
step-in load current is applied, there are two components to the regulator’s response. There is an instantaneous step in the output voltage due to the output
capacitor’s ESR and the regulator’s finite output impedance. The second, slower component is the regulator’s
active correction to the output voltage. Typical step
changes in the OUT load current from 10mA to 20mA
produce 20mV transients.
Power-Good Output (PGOOD)
The MAX8718/MAX8719 include an independent
power-good monitor. This circuit has an uncommitted
sense input (VCC) that can be connected to the regulator’s output or similar voltage. In the MAX8718, the
comparator threshold tracks the output set point
according to the state of 5/3. In the MAX8719, the comparator threshold is set to the feedback reference voltage. The PGOOD output goes high when V CC is
greater than -10% of the regulation set point. There is a
fixed 100ms (min) delay when the output goes into regulation, which helps ensure proper output-voltage settling. The PGOOD delay when transitioning out of
regulation is much faster, 4.5µs (typ), which permits the
system to respond as fast as possible to the out-of-regulation condition.
The power-good monitor has an open-drain output,
which can be externally pulled up to OUT. The voltage
rating for PGOOD is 28V.
Layout Guidelines
Good layout is important to minimize the effects of
noise and ensure accurate voltage regulation. Use
appropriate trace widths for the high-current paths and
keep traces short to minimize parasitic inductance and
capacitance. Figure 4 shows a layout of the high-current paths. Place bypass capacitors close to the IN and
OUT pins. When using the MAX8719, the feedback
resistors should be placed close to the device to avoid
voltage drops on ground that may shift the output voltage. Connect the exposed backside paddle to as large
a copper area as practical.
