TPS51100DGQR

Texas Instruments · Power Management - Specialized · MSOP-10-EP

TPS51100DGQR from Texas Instruments, in a MSOP-10-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDDQSNS input VDDQ sense input. Internal divider produces VDDQSNS/2 as the reference for VTT and VTTREF. Input current typ 3 µA (max 5 µA). Recommended range −0.1 V to 3.6 V.
2 VLDOIN power_in Power supply for the VTT LDO and VTTREF output stage. Recommended range −0.1 V to 3.6 V (typically 1.2 V to 3.6 V per features). Supply current typ 1.2 mA.
3 VTT power_out Power output for the VTT LDO. Regulates to VDDQSNS/2 (typ 1.25 V when VLDOIN=VDDQSNS=2.5 V). 3-A sink/source current capability with typical ±20 mV accuracy.
4 PGND power_in Power ground output for the VTT LDO. Return path for high-current VTT sink/source. Recommended voltage range −0.1 V to 0.1 V relative to signal ground.
5 VTTSNS input Voltage sense input for the VTT LDO. Connect to the plus terminal of the VTT output capacitor for remote sensing. Input current typ −0.25 µA.
6 VTTREF output VTT reference (buffered) output, 10-mA drive capability. Regulates to VDDQSNS/2. Connect to GND through a 0.1-µF ceramic capacitor.
7 S3 input S3 sleep-state signal input. When asserted, places VTT into Hi-Z (suspend-to-RAM) while keeping VTTREF alive. Recommended range −0.10 V to 5.25 V.
8 GND power_in Signal ground. Connect to the negative terminal of the output capacitor. Reference for VIN, control logic, and VTTREF.
9 S5 input S5 sleep-state signal input. When asserted, soft-off for VTT and VTTREF (suspend-to-disk). Recommended range −0.10 V to 5.25 V.
10 VIN power_in 5-V power supply for internal bias/control. Recommended supply voltage 4.75 V to 5.25 V. Supply current typ 0.5 mA (no load).
