Richtek Tech · Linear Voltage Regulators (LDO) · MSOP-10-EP
RT9026GFP from Richtek Tech, in a MSOP-10-EP. 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 | VDDQSNS | input | VDDQSNS sense input pin; the internal divider tracks 1/2 VDDQSNS for both VTT and VTTREF, with VDDQSNS input current specified at 50 µA max (VIN = 5V, S5 = S3 = 5V). |
| 2 | VLDOIN | power_in | Power supply of the VTT and VTTREF output stage (powers the MOS), with a recommended supply range of 1.2V to 3.3V. |
| 3 | VTT | power_out | Termination output voltage for connection to termination resistors, equal to VDDQSNS/2, with source/sink current limits of 3A min and 4A typ. |
| 4 | PGND | power_in | Power ground of the VTT output stage. |
| 5 | VTTSNS | input | VTT voltage sense input; connect to the plus terminal of the output capacitor. |
| 6 | VTTREF | power_out | Buffered reference output equal to VDDQSNS/2, supporting up to 10mA sourcing and sinking. |
| 7 | S3 | input | Active-low suspend-to-RAM mode control pin: when low, VTT is turned off and left High-Z while VTTREF remains active; logic-high input minimum is 1.6V and logic-low maximum is 0.4V. |
| 8 | GND | power_in | Ground pin; it must be connected to the exposed pad and the PCB ground plane. |
| 9 | S5 | input | Active-low shutdown control pin: when low, both VTT and VTTREF are turned off and discharged to ground. |
| 10 | VIN | power_in | Analog input pin (to control loop), with a supply range of 3.15V to 5.5V. |
| 11 | GND | power_in | Exposed thermal pad ground; it must be soldered to a large PCB and connected to GND for maximum power dissipation. |
