SK6013BS5-33

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

SK6013BS5-33 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 voltage. Recommended operating range 2.5V to 6.5V (absolute max -0.3V to 8V). Bypass with a 1uF ceramic capacitor to GND.
2 GND power_in Ground reference for the device.
3 EN input Enable input, active high. Do not float. V_ENH >= 1.2V enables the regulator; V_ENL <= 0.4V disables it (shutdown current <1uA). EN input current max 1uA over 0-5.5V.
4 NC unconnected Not connected. Leave floating or tie to GND for mechanical support.
5 VOUT power_out Regulated output. Factory-set to 3.3V for the -33 suffix. Maximum output current 400mA (V_IN-V_OUT >= 0.5V); dropout typ 220mV at 200mA. Bypass with a 1uF ceramic capacitor to GND. Fast VOUT discharge is enabled in the BS5 variant.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Suntek datasheet (12 pp, sha256 076af2dee2844a1a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
