LP2998QMRE

Texas Instruments · Power Management - Specialized · SO-8

LP2998QMRE from Texas Instruments, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference pin for the regulator.
2 SD input Active-low shutdown pin that tri-states VTT when pulled low; it has an internal pull-up so it can be tied to AVIN or left open to enable the part, and the SD input is rated 0 V to AVIN.
3 VSENSE input Feedback pin for regulating VTT, best connected to the middle of the termination bus for remote load regulation, and it must still be connected to VTT if remote regulation is not used.
4 VREF power_in Buffered output of the internal reference VDDQ/2 for the chipset and DIMMs, which stays active during shutdown and thermal shutdown and should draw very little current.
5 VDDQ input Input used to create the internal reference equal to VDDQ/2 that sets VTT, best connected as a remote sense to the DIMM 2.5 V rail, and limited to a maximum of 6 V (or less than 2 x (AVIN - 1)).
6 AVIN power_in Input supply for all internal control circuitry, specified at 2.2 V to 5.5 V relative to GND.
7 PVIN power_in Power input for the VTT output stage that must be equal to or lower than AVIN, with 0 V to AVIN recommended and rails at or below 3.3 V advised to avoid thermal limiting.
8 VTT power_out Regulated output that sources and sinks current to terminate the bus resistors at VDDQ/2, rated for 1.5 A continuous and transient peaks up to 3 A.
