DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC70-5
DS8561-33C5 from DSTECH, in a SC70-5. 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 | VIN | power_in | Power input; operating range 1.2V to 5.5V (absolute max 7V), bypass with 1uF or larger capacitor placed close to VIN and GND. |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable control; VIH 1.0V rising, VIL 0.4V falling, pulling it low enters shutdown with 0.1uA typical shutdown current. |
| 4 | NC | unconnected | Floating pin, no internal connection. |
| 5 | VOUT | power_out | Regulated voltage output (3.3V fixed for -33), up to 300mA, stable with 1uF to 22uF ceramic output capacitor. |
