AP2125KS-2.8TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

AP2125KS-2.8TRG1 from Diodes Incorporated, in a SC-70-5. 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 Unregulated input voltage. Operating range VOUT+0.5V to 6V; absolute maximum 6.5V. Bypass with 1µF ceramic to GND close to the pin.
2 GND power_in Device ground reference for the internal reference, error amplifier, and output feedback divider.
3 CE input Active-high chip-enable input. Logic high (>=1.5V) enables the regulator; logic low (<=0.4V) shuts it down (ISTD ~0.01µA typ). Allowed range -0.3V to VIN+0.3V; do not leave floating.
4 NC unconnected No internal connection. Leave floating or tie to GND as convenient for layout.
5 VOUT power_out Regulated 2.8V output, 300mA (min). Stable with low-ESR ceramic capacitors; 1µF COUT recommended. Short-circuit current-limited (~50mA at VOUT=0V) with thermal protection at +160°C.
