TPS51200DRCR from Texas Instruments, in a VSON-10-EP(3x3). 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 | REFIN | input | Reference input. REFIN voltage range 0.5V to 1.8V; typically driven directly or via a resistor divider from VDDQ to set the LDO regulation target (VO = REFIN). |
| 2 | VLDOIN | power_in | Supply voltage for the LDO pass devices. VLDOIN operating range 1.1V to 3.5V; sources the sink/source termination current for VTT. |
| 3 | VO | power_out | Power output for the LDO (VTT termination rail). Sink/source current limit ~3-5.5A; requires a minimum 20µF (typically 3×10µF MLCC) output capacitance. |
| 4 | PGND | power_in | Power ground for the LDO. Connected to the thermal pad; PGND-to-GND rating ±0.3V absolute max. |
| 5 | VOSNS | input | Voltage sense input for the LDO (remote sense). Connect to the positive terminal of the output capacitor or directly to the load for accurate regulation. |
| 6 | REFOUT | output | Buffered reference output (VTTREF), ±10mA capability, tracks REFIN. Requires a 0.1µF ceramic to GND; total capacitance on REFOUT must remain below 0.47µF and the pin cannot be left open. |
| 7 | EN | input | Enable input. For DDR VTT applications tie EN to SLP_S3; otherwise use as a logic ON/OFF. Input range up to 6.5V absolute max, 3.5V recommended. |
| 8 | GND | power_in | Signal ground reference for the controller and reference circuitry. |
| 9 | PGOOD | output | Open-drain power-good indicator. Asserts high (via external pull-up) when VOSNS is within ±20% of REFOUT; VOL ≤ 0.4V at 4mA sink. |
| 10 | VIN | power_in | 2.5V or 3.3V controller power supply (recommended 2.375V-3.5V). Requires a 1µF-4.7µF ceramic decoupling capacitor. |
| 11 | PAD | power_in | Exposed thermal pad on the underside of the VSON-10 package. Must be soldered to the PCB ground plane for thermal dissipation; connected to PGND. |
