AP2210K-2.5TRG1

Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-23-5

AP2210K-2.5TRG1 from Diodes Incorporated, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input voltage supply pin, with a recommended input range of VOUT+1V to 13.2V and a supply voltage range of 2.5V to 13.2V.
2 GND power_in Ground reference pin for the regulator.
3 EN input Enable input, CMOS or TTL compatible: logic high enables the regulator and logic low shuts it down, with an enable input voltage range of 0 to 13.2V.
4 BYP/ADJ passive Bypass capacitor connection for low-noise operation (no more than 100pF recommended on fixed versions) or the adjustable output feedback pin on the ADJ version.
5 VOUT power_out Regulated output voltage; an output capacitor of at least 1.0µF is required to prevent oscillation, or 2.2µF when a 100pF CBYP is used.
