General Description
The MAX5086 high-voltage linear regulator operates
from a 6.5V to 45V input voltage and delivers up to
a 250mA output current. The device consumes only
70µA of quiescent current with no load and 13µA in
shutdown. The device includes a SET input, that when
connected to ground, selects a preset output voltage of
3.3V (MAX5086A) or 5.0V (MAX5086B). Alternatively,
the output voltage can be adjusted from 2.5V to 11V by
simply connecting SET to the regulator’s output through a
resistive divider network. The MAX5086 also provides an
open-drain, active-low microprocessor reset output that
asserts when the regulator output drops below the preset
output voltage threshold. An external capacitor programs
the reset timeout period. Other features include an enable
input, thermal shutdown, and short-circuit protection.
The MAX5086 operates over the automotive temperature
range of -40°C to +125°C and is available in a 16-pin
TQFN thermally enhanced package.

Detailed Description
The MAX5086 high-voltage linear regulator includes an
integrated microprocessor reset circuit with an adjustable
reset timeout period (see the Adjustable Reset Timeout
Period (CT) section). The device guarantees a 250mA
load current and is available with a preset output voltage
of 3.3V (MAX5086A) or 5V (MAX5086B). Both devices
can be configured to provide an adjustable output voltage
from 2.5V to 11V. The internal reset circuit monitors the
regulator output voltage and asserts RESET low when the
regulator output falls below the reset threshold voltage.
Other features include an enable (regulator control input),
21µA (max) shutdown current, short-circuit protection
(see the Output Short-Circuit Current Limit section), and
thermal shutdown (see the Thermal Protection section).
Regulator
The MAX5086 accepts an input voltage range from 6.5V
to 45V and offers a fixed output voltage of 3.3V or 5V. For
an adjustable output voltage operation, use an external
resistive divider network connected between OUT, SET,
and GND (see Figure 2).
Enable Input (EN)
EN is a logic-level enable input that turns ON/OFF the
device. Drive EN high to turn on the device and drive EN
low to place the device in shutdown. The MAX5086 draws
13µA (typ) of supply current when in shutdown. EN with-
stands voltages up to +45V, allowing EN to be connected
to IN for an always-on operation.
Remote Sensing (OUTSENSE)
For fixed output voltage versions, OUTSENSE must be
used for load voltage sensing. Leave OUTSENSE open
circuit when using adjustable output voltage version.
Reset Output (RESET)
A supervisor circuit is fully integrated in the MAX5086 and
uses the same reference voltage as the regulator. RESET
goes low if VOUT drops below the preset output voltage
threshold, and remains low at least for the timeout period
after VOUT rises above the reset voltage threshold.
Adjustable Reset Timeout Period (CT)
The MAX5086 features a user-adjustable reset timeout.
Connect a capacitor from CT to GND to set the reset time-
out period (see Figure 2) and use the following equation
to calculate the timeout period:
tRP = CCT x 0.6175 x 106
where CCT is the value of the external capacitor con-
nected from CT to GND and tRP is in seconds.
Thermal Protection
When the junction temperature exceeds TJ = 175°C an
internal thermal sensor signals the shutdown logic, which
turns off the pass transistor, allowing the IC to cool. The
thermal sensor turns the pass transistor on again after
the IC’s junction temperature cools by 25°C, resulting in
a cycled output during continuous thermal-overload con-
ditions. Thermal protection protects the MAX5086 in the
event of fault conditions. During continuous operation, do
not exceed the absolute maximum junction temperature
rating of TJ = +150°C.
Output Short-Circuit Current Limit
The MAX5086 features a current limit. The output can
be shorted to GND for an indefinite period of time (for
VIN < 16V) without damage to the device.

Applications Information
Output Voltage Selection
The MAX5086 features dual-mode operation, in either
a preset voltage mode or an adjustable mode. In pre-
set voltage mode, internal feedback resistors set the
MAX5086’s output voltage to +3.3V or +5V. Select preset
voltage mode by connecting SET to ground. In adjustable
mode, select an output between +2.5V and +11V using
two external resistors connected as a voltage-divider to
SET (Figure 2). Set the output voltage using the following
equation:
OUT SET R1
V V x 1 R2
= +
where VSET = 1.23V and R2 is chosen to be approxi-
mately 100kΩ.
Available Output Current Calculation
The MAX5086 high-voltage regulator provides up to
250mA of output current. The input voltage extends to
+45V. Package power dissipation limits the amount of
output current available for a given input/output voltage
and ambient temperature. Figure 3 depicts the maximum
power dissipation curve for these devices. The graph
assumes that the exposed pad of the MAX5086 package
is set up per JEDEC specifications.
Use Figure 3 to determine the allowable package dissipa-
tion (PD) for a given ambient temperature. Alternately, use
the following formula to calculate the allowable package
dissipation:

Output Capacitor Selection and
Regulator Stability
For stable operation over the full temperature range and
with load currents up to 250mA, use a 15µF (min) output
capacitor with an ESR < 0.25Ω. To reduce noise and
improve load-transient response, stability, and power-
supply rejection, use larger output capacitor values such
as 22µF.
Some ceramic capacitor dielectrics exhibit large capaci-
tance and ESR variation with temperature. For capacitor
dielectrics such as Y5V, use 22µF or more to ensure
stability at temperatures below -10°C. With X7R or X5R
dielectrics, 15µF should be sufficient at all operating tem-
peratures. To improve power supply rejection and tran-
sient response, use a minimum 47µF low ESR capacitor
from IN to GND.
