45V, 400mA, Low-Quiescent-Current
Linear Regulator with Adjustable Reset Delay
General Description
Features
● Wide Operating Input Voltage Range (6.5V to 45V)
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 resis-
tive 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 features include an enable
input, thermal shutdown, and short-circuit protection.

45V, 400mA, Low-Quiescent-Current
Linear Regulator with Adjustable Reset Delay
Detailed Description
The MAX5087 high-voltage linear regulator includes
an integrated μP reset circuit with an adjustable reset
timeout period (see the Adjustable Reset Timeout Period
(CT) section). The device guarantees a 400mA load cur-
rent 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 regula-
tor output voltage and asserts RESET low when the regu-
lator 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).

Figure 2. Setting the Adjustable Output Voltage
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).
Adjustable Reset Timeout Period (CT)
The MAX5087 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:
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 with-
stands voltages up to +45V, allowing EN to be connected
to IN for an always-on operation.

t

RP
CT
where C
is the value of the external capacitor con-
CT
nected from CT to GND.
Thermal Protection
When the junction temperature exceeds T = +175°C, an
J
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 thermaloverload condi-
tions. Thermal protection protects the MAX5087 in the
event of fault conditions. During continuous operation, do
not exceed the absolute maximum junction temperature
Remote Sensing (OUTSENSE)
The 3.3V (MAX5087A) and 5V (MAX5087B) output
voltage 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
rating of T = +150°C.
J
uses the same reference voltage as the regulator. RESET
goes low if V
drops below the preset output voltage
OUT
Output Short-Circuit Current Limit
The MAX5087 features a current limit. The output can be
threshold, and remains low at least for the timeout period
after V rises above the reset voltage threshold.
OUT
shorted to GND for an indefinite period of time (for V
<

short-circuit protection is only guaranteed for V < 14V.

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 voltage-divider to
SET (Figure 2). Set the output voltage using the following
equation:

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 out-
put current available for a given input/output voltage and
ambient temperature. Figure 3 shows the maximum 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.
The above equations do not include the negligible power
dissipation from self-heating due to the IC ground current.

Output-Capacitor Selection and
Regulator Stability
And find the maximum output current:
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 values such
as 22μF.

In example 3 the maximum output current is calculated
as 666mA, however, the maximum output current cannot
exceed 400mA.
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.
Use Figure 4 to quickly determine maximum allowable
output current for selected ambient temperatures.
