General Description
The MAX5087 high-voltage linear regulator operates
from an input voltage of 6.5V to 45V and delivers up to
400mA of output current. The device consumes only
70µA of quiescent current with no load and 11µA in
shutdown. The device includes a SET input, that when
connected to ground, selects a preset output voltage of
3.3V (MAX5087A) or 5.0V (MAX5087B). 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 MAX5087 also provides
an open-drain, active-low microprocessor (µP) reset
output that asserts when the regulator output drops
below the preset output voltage threshold. An external
capacitor programs the reset timeout period. Other fea-
tures include an enable input, thermal shutdown, and
short-circuit protection.
The MAX5087 operates over the automotive tempera-
ture range of -40°C to +125°C and is available in a 16-
pin TQFN thermally enhanced package.

Detailed Description
The MAX5087 high-voltage linear regulator includes an
integrated µP reset circuit with an adjustable reset time-
out period (see the
Adjustable Reset Timeout Period
(CT)
section). The device guarantees a 400mA load
current and is available with a preset output voltage of
3.3V (MAX5087A) or 5V (MAX5087B). 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 MAX5087 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 the device
on/off. Drive EN high to turn on the device and drive EN
low to place the device in shutdown. The MAX5087
draws 11µA (typ) of supply current when in shutdown.
EN withstands voltages up to +45V, allowing EN to be
connected to IN for an always-on operation.
Remote Sensing (OUTSENSE)
The 3.3V (MAX5087A) and 5V (MAX5087B) output volt-
age versions connect OUTSENSE for load voltage
sensing. Leave OUTSENSE open when using
adjustable output voltage version.
Reset Output (
RESET
)
A supervisor circuit is fully integrated in the MAX5087
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 time-
out period after VOUT rises above the reset voltage
threshold.
Adjustable Reset Timeout Period (CT)
The MAX5087 features a user-adjustable reset timeout.
Connect a capacitor from CT to GND to set the reset
timeout period (see Figure 2) and use the following
equation to calculate the timeout period:
tRP = CCT x 0.6175 x 106(s)
where CCT is the value of the external capacitor con-
nected from CT to GND.
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 conditions. Thermal protection protects the
MAX5087 in the event of fault conditions. During contin-
uous operation, do not exceed the absolute maximum
junction temperature rating of TJ= +150°C.
Output Short-Circuit Current Limit
The MAX5087 features a current limit. The output can
be shorted to GND for an indefinite period of time (for
VIN < 14V) without damage to the device. Continuous
output short-circuit protection is only guaranteed for
VIN < 14V.

Applications Information
Output-Voltage Selection
The MAX5087 features a Dual ModeTM operation, in
either a preset-voltage mode or an adjustable mode. In
preset-voltage mode, internal feedback resistors set
the MAX5087’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 volt-
age-divider to SET (Figure 2). Set the output voltage
using the following equation:
where VSET = 1.235V and R2 is chosen to be < 100kΩ.
Available Output-Current Calculation
The MAX5087 high-voltage regulator provides up to
400mA 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 shows the maxi-
mum power dissipation curve for these devices. The
graph assumes that the exposed paddle of the MAX5087
package is set up per JEDEC 51 (multilayer board)
specifications.
Use Figure 3 to determine the allowable package dissi-
pation (PD) for a given ambient temperature.
Alternately, use the following formulas to calculate the
allowable package dissipation. Note that for the exam-
ples shown below, the electrical characteristic limits are
guaranteed up to TJ= +125°C (max).
After determining the allowable package dissipation
calculate the maximum output current using the follow-
ing formula:
The above equations do not include the negligible
power dissipation from self-heating due to the IC
ground current.
Example 1:
TA= +95°C
VIN = +14V
VOUT = +5V
Find the maximum allowable output current. First calcu-
late package dissipation at the given temperature as
follows:
Then determine the maximum output current:

Output-Capacitor Selection and
Regulator Stability
For stable operation over the full temperature range
and with load currents up to 400mA, 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 val-
ues such as 22µF.
Some ceramic capacitor dielectrics exhibit large
capacitance 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 oper-
ating temperatures. To improve power supply rejection
and transient response, use a minimum 47µF low-ESR
capacitor from IN to GND.
