MAX16999
Ultra-Low Output Voltage, Low-Quiescent-Current
Linear Regulator for High-Temperature Applications
General Description
Features
● Preset 0.5V to 3.3V Output Voltage Range
The MAX16999 linear regulator operates from a 2.5V to
5.5V input voltage and delivers 100mA continuous load
current with a low quiescent current typically around
13μA. The output voltage is preset to internally trimmed
voltages in the 0.5V to 3.3V range (see the Selector
Guide). An active-low, open-drain reset output remains
low for a programmable timeout delay after the output
voltage reaches regulation. The reset timeout is pro-
grammed by an external capacitor connected to CRES.
● Up to 100mA Output Current at T = +125°C
A
● 13μA Quiescent Current
● Logic-Controlled Enable
● Adjustable POR Delay Flag
● Short to GND Protection on Reset Timer
● Used in Parallel with High-Current Supply of Equal
Voltages
This device also features logic-controlled shutdown, and
short-circuit and thermal-overload protection. The typical
applications are multimedia, telematics, and motor control
microcontrollers (μCs) with always-on requirements. The
MAX16999 is used as a parallel, lowquiescent supply to
power the core or interrupt section of μCs during sleep
mode. It can also be used to supply a timer or memory
during μC shutoff. The adjustable POR delay assists with
power-supply sequencing.

CRES
The MAX16999 is a low-quiescent-current linear regula-
tor designed for applications requiring high reliability. This
device can supply loads up to 100mA and is available in
factory-preset output voltages from 0.5V to 3.3V (see the
Selector Guide). As illustrated in Figure 1, the MAX16999
linear regulator consists of a reference, an error amplifier,
a p-channel MOSFET pass transistor, and an internal
feedback voltage-divider. A power-on reset section signals
if the output voltage has come out of regulation. The reset
signal timeout is defined by the charging time of an exter-
nal capacitor attached to CRES.

The second timer is an internal fault timer and ensures the
regulator does not stay off indefinitely because of a fault
on CRES such as a short. The fault timer runs for a maxi-
mum of 100ms. A logic block monitors both internal timers
to determine the shortest timeout. If the first timeout is the
fault timer, the pullup current is switched off in order to
avoid unnecessary current consumption and a resistive
To increase system reliability, the MAX16999 features a
POR reset timeout along with overcurrent and overtem-
perature protection. A power-on reset timeout guarantees
startup even with a faulty timing capacitor. Parameters
are guaranteed up to +125°C junction temperature. The

becomes disconnected.

(typ) the fault timer defines the timeout behavior.
Current Limit
Logic-Controlled Enable
Once the output voltage reaches regulation, the output
current is limited to 150mA (typ). If the output current
exceeds the current limit, the output voltage begins to
decrease.
The MAX16999 provides a logic-enable input (EN). For
normal operation drive EN to logic-high. When EN is driv-
en high, the linear regulator starts to regulate by increas-
ing the output voltage up to the preset value. To disable
the device, drive EN low to set OUT to high impedance—
this enables a pulldown current from CRES to discharge
the capacitor. Once the device is disabled, the input sup-
ply current reduces to less than 0.3μA. The EN input is
latched into its last state by a 120kΩ internal resistor. To
change state, the latch needs to be overridden. When EN
is low, the RESET output is high impedance.
Thermal-Overload Protection
Thermal-overload protection limits total power dissipa-
tion in the MAX16999. When the junction temperature
exceeds +165°C, a thermal sensor turns off the pass tran-
sistor, allowing the IC to cool. The thermal sensor turns
the pass transistor on again after the junction temperature
cools by 15°C, resulting in a pulsed output during con-
tinuous thermal-overload conditions. Thermal-overload
protection safeguards the MAX16999 in the event of fault
conditions. For continuous operation, do not exceed the
absolute maximum junctiontemperature rating of +150°C.

Using MAX16999 in Parallel
with Another Supply
The MAX16999 can be used in parallel with another sup-
ply of equal voltage (see Figure 2). The circuit shows a
typical low-power solution for a μC.
Undervoltage Lockout (UVLO)
Before the MAX16999 can operate, the input voltage
must exceed the UVLO threshold of 2.2V (max) with a
30mV hysteresis. If the input voltage is below the UVLO
threshold, OUT becomes high impedance and EN is
ignored regardless if it is driven high or low.
