# DS8570D10

**DSTECH** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN3x3-10L

DS8570D10 from DSTECH, in a DFN3x3-10L. 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 | VOUT | power_out | Regulator output; VOUT is set by VOUT = VREF x (R1+R2)/R2 with VREF of 0.8V typical, and the output capacitor should be at least 10µF ceramic. |
| 2 | VOUT | power_out | Regulator output; VOUT is set by VOUT = VREF x (R1+R2)/R2 with VREF of 0.8V typical, and the output capacitor should be at least 10µF ceramic. |
| 3 | VOUT | power_out | Regulator output; VOUT is set by VOUT = VREF x (R1+R2)/R2 with VREF of 0.8V typical, and the output capacitor should be at least 10µF ceramic. |
| 4 | FB | input | Output voltage setting input; VOUT = VREF x (R1+R2)/R2, and R1 and R2 should each be more than 10kΩ to reduce power loss. |
| 5 | POK | output | Open-drain power-good output that goes high when VOUT reaches 90% of its rated value, and requires an external pull-up (100kΩ to VOUT suggested). |
| 6 | EN | input | Enable control input with logic-high at 1.2V minimum and logic-low at 0.4V maximum; the regulator is off when EN is low or floating because the pin is internally pulled low. |
| 7 | VIN | power_in | Input supply voltage, specified from 1V to 5.5V in the recommended operating conditions. |
| 8 | VIN | power_in | Input supply voltage, specified from 1V to 5.5V in the recommended operating conditions. |
| 9 | VIN | power_in | Input supply voltage, specified from 1V to 5.5V in the recommended operating conditions. |
| 10 | VCC | power_in | Control circuit supply voltage, specified from 3V to 5.5V with VCC greater than VOUT + 1.5V. |
| 11 | GND | power_in | Ground; the exposed pad must be soldered to a large PCB and connected to GND for maximum power dissipation. |
