},
{
"number": "2",
"name": "VCC",
"type": "power_out",
"description": "VCC is the internal LDO output that requires a ceramic capacitor of at least 470 nF to filter the internal voltage reference and supplies the embedded analog circuitry."

"number": "3",
"name": "SS/INH",
"type": "input",
"description": "Pulling this pin to GND with an open-collector stage disables the device (INH mode), and an internal 4 A typical current generator charges the external soft-start capacitor."

"name": "SYNCH",
"type": "input",
"description": "This pin provides master/slave synchronization and should be left floating when not used in LNM."

"number": "6",
"name": "MLF",
"type": "input",
"description": "A pull-up resistor (E24 series) to VCC or pull-down to GND selects low noise or low consumption mode and the active RST threshold, with pinstrapping active only before the soft-start phase."

{
"number": "8",
"name": "DELAY",
"type": "passive",
"description": "An external capacitor on this pin sets the time delay before the RST open-collector output is asserted after the output exceeds the reset threshold, and if left floating RST acts like a power good."
