Pin Functions

PIN I/O DESCRIPTION
NAME NO.
VTTREF 1 O Reference output. Connect to GND through 0.1-µF ceramic capacitor.
VDDQSNS 2 I VDDQ sense input. Reference input for VTTREF.
VLDOIN 3 I Supply voltage for the LDO. Connect to VDDQ voltage or an alternate voltage source.
4
5
PGND 6 — Power ground. Connect output for the VTT/ V O LDO to negative pin of the output capacitor.
7
8
EN 9 I Enable pin. Driving this pin to logic high enables the device; driving this pin to logic low disables the device.
VDD/VIN 10 I 2.5- or 3.3-V power supply. A ceramic decoupling capacitor with a value between 1 and 10 µF is required.
PGOOD 11 O PGOOD output pin. PGOOD pin is an open drain output to indicate the output voltage is within specification.
VTT/VO 12 O Power output for VTT LDO
13
14
AGND 15 — Signal ground. Connect to negative pin of output capacitors.(1)
VTTSNS 16 I VDDQ sense input, reference input for VTTREF. Voltage sense for VTT/ V O . Connect to positive pin of the output capacitor or the load.
(1) Thermal pad must be connected to GND.
