Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-5

SL42764 from Slkor SLKORMICRO Elec, in a TO-252-5. 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 I power_in Input supply pin (VI). Operating range 5 V to 42 V (absolute max ±42 V). Bypass with a ceramic capacitor placed close to the IC and returned directly to GND.
2 EN input Enable input, active high. VEN.H ≥ 3.5 V turns the regulator on; VEN.L ≤ 0.5 V shuts it down (shutdown current < 10 µA). Internal pull-down current 0.1-3 µA at VEN=5 V; no external pull-up required.
3 GND power_in Ground. Internally connected to the exposed heat-sink tab; the tab should be soldered to the PCB ground/heat-spreader plane.
4 VA input Voltage adjust (feedback) input for the ADJ version. Connect to the R1/R2 divider from Q to set VQ = ((R1+R2)/R2)·Vref, with Vref=2.5 V. For the fixed-voltage version this pin is n.c. (leave open or tie to GND).
5 Q power_out Regulated output. Adjustable 2.5 V-20 V, up to 400 mA (typ 500 mV dropout at 250 mA). Requires an output capacitor CQ ≥ 22 µF with ESR ≤ 3 Ω to ground for loop stability.
