45V, 250mA, Low-Quiescent-Current
Linear Regulator with Adjustable Reset Delay
MAX5086
General Description
Features
♦ Wide Operating Input Voltage Range (6.5V to 45V)
♦ Thermally Enhanced Package Dissipates
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 shut-
down. The device includes a SET input, that when con-
nected 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.

Stresses 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.

45V, 250mA, Low-Quiescent-Current
Linear Regulator with Adjustable Reset Delay
Detailed Description
The MAX5086 high-voltage linear regulator includes an
6.5V TO 45V
2.5V TO 11V
15μF
integrated microprocessor reset circuit with an
adjustable reset timeout period (see the Adjustable
Reset Timeout Period (CT) section). The device guaran-
tees a 250mA load current and is available with a pre-
set output voltage of 3.3V (MAX5086A) or 5V
(MAX5086B). Both devices can be configured to pro-
vide an adjustable output voltage from 2.5V to 11V. The
internal reset circuit monitors the regulator output volt-
age 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).

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).
Figure 2. Setting the Adjustable Output Voltage
Adjustable Reset Timeout Period (CT)
The MAX5086 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:

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 withstands voltages up to +45V, allowing EN to be
connected to IN for an always-on operation.

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 maxi-
mum power dissipation curve for these devices. The
graph assumes that the exposed pad of the MAX5086
package is set up per JEDEC specifications.

Find the maximum allowable output current. First calcu-

Alternately, use the following formula to calculate the

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.

(14V)−(5V)
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
operating temperatures. To improve power supply
rejection and transient response, use a minimum 47µF
low ESR capacitor from IN to GND.

In Example 3, the maximum output current is calculated
as 296mA, however, the maximum output current can-
not exceed 250mA.
Use Figure 4 to quickly determine maximum allowable
output current for selected ambient temperatures.
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)
