EN and
HOLD
. Figure 3 shows the timing diagram for the
enable and hold functions. Connecting
HOLD
to OUT or
floating
HOLD
allows the EN input to act as a standard
ON/
OFF
switch for the regulator output.
Thermal Protection
When the junction temperature exceeds T
J
= +150
°
C, an
internal thermal sensor signals the shutdown logic that
turns off the pass transistor and allows the IC to cool.
The thermal sensor turns the pass transistor on again
after the IC
’
s junction temperature cools by 20
°
C, result-
ing in a cycled output during continuous thermal-over-
load conditions. Thermal protection protects the
MAX5023/MAX5024 in the event of fault conditions. For
continuous operation, do not exceed the absolute maxi-
mum junction temperature rating of T
J
= +150
°
C.
Applications Information
Output Voltage Selection (MAX5024 only)
The MAX5024 features Dual Mode
operation: it oper-
ates in either a preset voltage mode or an adjustable
mode. In preset voltage mode, internal trimmed feed-
back resistors set the MAX5024
’
s internal linear
regulator to +3.3V or +5V (see the
Selector Guide
).
