KEXIN · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
HT7133 from KEXIN, in a SOT-89-3. 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 | GND | power_in | Device ground return. Should be tied to system single-point ground per the application circuit. |
| 2 | VIN | power_in | Unregulated positive supply input, -0.3 V to 28 V absolute max, 4.5 V to 24 V normal operating range for the 3.3 V variant. Bypass with a 10 uF capacitor to GND as shown in the basic application circuit. |
| 3 | VOUT | power_out | Regulated 3.3 V ±5% output (HT7133), 30 mA typical / 20 mA min output current. Requires a 10 uF output capacitor to GND for stability. |
