SK6513SS5E-36

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

SK6513SS5E-36 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 IN power_in Supply input pin. Accepts 2.5V to 36V input (absolute max 44V). Decouple with a 1µF-10µF ceramic capacitor to GND placed close to the device for stability and noise suppression.
2 GND power_in Ground reference for the LDO. Provide a wide copper trace / ground plane connection close to the input and output capacitors for best thermal and noise performance.
3 EN input Enable control input, active high. VENH ≥ 1.2V enables the regulator; VENL ≤ 0.4V puts the device in shutdown (IQ_OFF ≈ 0.1µA typ). EN input current is ~1µA over 0V to 36V. Do not float; tie to VIN if always-on operation is desired.
4 NC unconnected No internal connection. May be left floating or tied to GND per PCB layout convenience.
5 OUT power_out Regulated output pin. Provides fixed output voltage (1.8V, 2.5V, 3.0V, 3.3V, 3.6V, or 5.0V per suffix XX) at up to 300mA (typical current limit 450mA). Requires a 1µF-10µF ceramic output capacitor (X7R/X5R, ESR 5-100mΩ) to GND placed close to the pin.
