MAX15006/MAX15007
40V, Ultra-Low Quiescent-Current
Linear Regulators in 6-Pin TDFN/8-Pin SO
Detailed Description
The MAX15006/MAX15007 high-voltage linear regulators
operate over a 4V to 40V input voltage range. These
devices guarantee 50mA load drive, and offer preset
output voltages of +3.3V (MAX15006A/MAX15007A) or
+5V (MAX15006B/MAX15007B) or an adjustable voltage
output from 1.8V to 10V (MAX15006C/MAX15007C).
Thermal shutdown and short-circuit protection prevent
damage during overtemperature and overcurrent condi-
tions. The MAX15007 includes an enable input (EN)
allowing the regulators to be turned on/off using a logic-
level voltage. Driving EN high turns on the device while
driving EN low places the device in a low-power shut-
down mode. In shutdown, the supply current is reduced
to 3μA (typ). The MAX15006/MAX15007 operate over the
-40°C to +125°C automotive temperature range. All
devices are available in thermally enhanced 6-pin TDFN
and 8-pin SO packages capable of dissipating 1.904W
and 1.860W at T A = +70°C, respectively.
Regulator
The regulator accepts an input voltage from 4V to 40V.
The MAX15006A/MAX15007A have a fixed 3.3V output
voltage while the MAX15006B/MAX15007B offer a fixed
5V output voltage. The MAX15006C/MAX15007C fea-
ture an adjustable voltage output by connecting an
external resistive divider from OUT to FB and to GND
(see the Output Voltage Setting section).

EN Input (MAX15007 Only)
EN is an active-high, logic-level enable input that turns
the device on or off. Drive EN high to turn the device
on. An internal 0.5 μA pulldown current keeps the
MAX15007 in shutdown mode when driven by a three-
state driver in high-impedance mode, or an open-drain
driver. While in shutdown, the device consumes only
3μA (typ). EN withstands voltages up to 40V, allowing it
to be driven by high input level voltages or connected
to IN for always-on operation.
Thermal Protection
When the junction temperature exceeds +165°C, an
internal thermal sensor turns the pass transistor off, and
allows the device to cool. The thermal sensor turns the
pass transistor on again after the junction temperature
cools by 20°C. This results in a cycled output during
continuous thermal-overload conditions. Thermal pro-
tection protects the MAX15006/MAX15007 in the event
of fault conditions. Operation at T J = +150°C without
going into thermal shutdown is not guaranteed. Use
Figures 3a and 3b to determine the minimum guaran-
teed output current.
Output Short-Circuit Current Limit
The MAX15006/MAX15007 feature a 175mA current
limit. The output can be shorted to GND for an indefinite
period of time without damage to the device. During a
short circuit, the power dissipated across the pass tran-
sistor can quickly heat the device. When the die tem-
perature reaches +165°C, the MAX15006/
MAX15007 shut down and automatically restart after
the die temperature cools by 20°C.
