AP2138N-1.5TRG1
Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-23-3
AP2138N-1.5TRG1 from Diodes Incorporated, in a SOT-23-3. 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 | GND | power_in | Ground reference pin for the regulator (listed as Ground in the pin description table for SOT-23-3). |
| 2 | VOUT | power_out | Regulated output voltage pin; the datasheet requires a minimum output capacitance of more than 1µF with ESR from 0.01Ω to 100Ω for stability. |
| 3 | VIN | power_in | Input voltage pin; recommended input voltage range is 2.5V to 6.0V, and a 1µF input filter capacitor is required. |
