FUNCTION
No Connection. Not internally connected.
Tracker Output. Bypass OUT_TRK to SGND with a 10μF (min) capacitor with low ESR
( ≤ 1.5 Ω ).
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.
Signal Ground
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.
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.
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.
Protector Gate Drive Output. Connect GATE to the gate of an external n-channel MOSFET.
GATE is the output of a charge pump with a 45μA pullup current to 7.1V (typ) above IN

GATE
during normal operation. GATE is quickly turned off through a 63mA internal pulldown
during an overvoltage condition. GATE then remains low until FB_PROT has decreased
96% below the threshold. GATE pulls low when EN_PROT is low.

REF
Output-Voltage Sense Input. Connect SOURCE to the source of the external n-channel
MOSFET.
1.235V Voltage Reference Output. Bypass REF to SGND with a 1nF or larger capacitor.
