FUNCTION
15
FB_LDO
FB_LDO
LDO Voltage Feedback Input. Connect FB_LDO to SGND to select the preset +5V
output voltage. Connect FB_LDO to an external resistive voltage-divider for adjustable
output operation. See the
Setting the Output Voltage
section.
16
EN_LDO
EN_LDO
Active-High LDO Enable Input. Connect EN_LDO to IN or to a logic-high voltage to
turn on the regulator. To place the LDO in shutdown, pull EN_LDO low or leave
unconnected and leave
HOLD
unconnected. EN_LDO is internally pulled to SGND
through a 1μA current sink. See the
Control Logic
section.
17
EN_SW
EN_SW
Active-High Switch Enable Input. Connect EN_SW to IN or to a logic-high voltage to
turn on the switch. Pull EN_SW low or leave unconnected to place the switch in
shutdown. EN_SW is internally pulled to SGND through a 1μA current sink.
18
EN_PROT
—
Protector Enable Input. Drive EN_PROT low to force GATE low and turn off the external
n-channel MOSFET. EN_PROT is internally pulled to SGND by a 1μA sink current.
Connect EN_PROT to IN for normal operation.
19, 20
IN
IN
Regulator Input. Bypass IN to SGND with a 10μF capacitor with an ESR < 1.5
Ω
.
21, 22
OUT_LDO
OUT_LDO
LDO Regulator Output. Bypass OUT_LDO to SGND with a ceramic capacitor with a
minimum value of 22μF. OUT_LDO has a fixed 5V output or can be adjusted from1.8V
to 11V. See the
Setting the Output Voltage
section.
23
OC_DELAY
OC_DELAY
Switch Overcurrent Blanking Time Programming Input. Leave OC_DELAY
unconnected to select the minimum delay timeout before turning the switch off.
OC_DELAY is internally pulled to SGND through a 1μA current source. See the
Programming the Switch Overcurrent Blanking Time
section.
24
ILIM
ILIM
Switch Current-Limit Set Input. Connect a 10k
Ω
to 200k
Ω
resistor from ILIM to SGND to
select the current limit for the internal switch. Connect ILIM to OUT_LDO to select the
internal 170mA (min) current-limit threshold. Do not leave ILIM unconnected. See the
Setting the Switch Current Limit
section.
25
HOLD
HOLD
Active-Low Hold Input. If EN_LDO is high when
HOLD
is forced low, the regulator
latches the state of the EN_LDO input and allows the regulator to remain turned on
when EN_LDO is subsequently pulled low. To shut down the regulator, release
HOLD
after EN_LDO is pulled low. If
HOLD
functionality is unused, connect
HOLD
to
OUT_LDO or leave unconnected.
HOLD
is internally pulled up to OUT_LDO through a
0.6μA current source. See the
Control Logic
section.
27, 28
OUT_SW
OUT_SW
Switch Output. Bypass OUT_SW to SGND with a minimum 0.1μF ceramic capacitor.

EP
EP
Exposed Pad. Connect EP to SGND plane. EP also functions as a heatsink to maximize
thermal dissipation. Do not use as the main ground connection.
