# SK6013BS5-28

**Suntek** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

SK6013BS5-28 from Suntek, in a SOT-23-5. 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 | VIN | power_in | Input supply, 2.5 V to 6.5 V (absolute max -0.3 V to 8 V). Bypass with 1 µF ceramic to GND close to the pin. |
| 2 | GND | power_in | Device ground reference. Common return for VIN, VOUT and EN. |
| 3 | EN | input | Enable input, active high; do not float. V_ENH ≥ 1.2 V enables the regulator; V_ENL ≤ 0.4 V shuts it down (shutdown current <1 µA). EN input current ≤ 1 µA for V_EN 0 to 5.5 V. |
| 4 | NC | unconnected | Not connected. Leave floating or tie to GND for mechanical stability. |
| 5 | VOUT | power_out | Regulated output, fixed 2.8 V for the -28 option (1.0 V-3.6 V in 0.1 V steps across the family). Up to 400 mA at V_IN−V_OUT = 0.5 V. Requires 1 µF ceramic to GND. BS5 suffix includes fast VOUT discharge when EN goes low. |
