N.C.
No Connection. Not internally connected.

OUT_TRK
Tracker Output. Bypass OUT_TRK to SGND with a 10μF (min) capacitor with low ESR
(
≤
1.5
Ω
).
4
4
ADJ
Tracker Amplifier Input. Connect ADJ to OUT_LDO or to an external source to track.
Alternatively, connect ADJ to REF to provide the reference voltage to the tracker.

SGND
Signal Ground
6
6
PGND
Ground. PGND is also the return path for the overvoltage protector pulldown current for
the MAX15008. In this case, connect PGND to SGND at the negative terminal of the
bypass capacitor connected to the source of the external MOSFET. For the MAX15010,
connect PGND to SGND together to the local ground plane.

7
RESET
Active-Low Open-Drain Reset Output.
RESET
is low while OUT_LDO is below the reset
threshold. Once OUT_LDO has exceeded the reset threshold,
RESET
remains low for
the duration of the reset timeout period before going high.

CT
Reset Timeout Adjust Input. Connect a capacitor (C
RESET
) from CT to ground to adjust
the reset timeout period. See the
Setting the
RESET
Timeout Period
section.

FB_PROT
Overvoltage Threshold Adjustment Input. Connect FB_PROT to an external resistive
voltage-divider network to adjust the desired overvoltage threshold. Use FB_PROT to
monitor a system input or output voltage. See the
Setting the Overvoltage Threshold
(MAX15008 Only)
section.

REF
1.235V Voltage Reference Output. Bypass REF to SGND with a 1nF or larger capacitor.
