SK6017S5-28

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

SK6017S5-28 from Suntek, in a SOT-23-5L. 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 Regulator input supply. Operating range 2.5V to 6.5V, absolute max -0.3V to 8V. Bypass with a 1uF ceramic capacitor to GND close to the pin.
2 GND power_in Device ground reference for both the input and output capacitor return paths.
3 CE input Chip Enable input, active high. VIH >=1.2V (up to VIN) enables the regulator; VIL <=0.4V puts the device into shutdown (<0.1uA typ). Must NOT be left floating; tie to VIN if always-on operation is required. Input current <=1uA over 0-5.5V.
4 NC unconnected Not internally connected. Leave floating or tie to GND on the PCB; do not use as a routing via since it may be bonded internally on some variants.
5 VOUT power_out Regulated LDO output. Factory-trimmed to the ordering-suffix voltage (S5-28 = 2.8V) with +/-2% accuracy. Sources up to 300mA (limited to 300mA typ current limit). Requires a 1uF ceramic output capacitor to GND for stability.
