High-Voltage, Low-Power Linear Regulators for Notebook Computers
General DescriptionThe 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 cur-
rent, the MAX8718/MAX8719 have good line- and load-
transient 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-volt-
age changes that occur during the switchover from bat-
tery 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-volt-
age applications (4V < VIN< 28V) such as smart batter-
ies, 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.

ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

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 VOUTdrops to 100mV below its nominal value as measured
with VINstarting 2V above VOUT.
Note 4:Specifications to -40°C are guaranteed by design, not production tested.
