HT7133H23

HX hengjiaxing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

HT7133H23 from HX hengjiaxing, in a SOT-23-3. 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 Ground reference (0 V). Must be tied to the system single-point ground; also the return for the internal bandgap reference and error amplifier.
2 VIN power_in Unregulated supply input, absolute maximum +30 V (recommended operating -0.3 V to +30 V). Bypass with a 10 µF polarized capacitor placed close to the pin.
3 VOUT power_out Regulated 3.3 V output (±2%), 100 mA maximum. A ceramic output capacitor >=2.2 µF (10 µF recommended) is required from VOUT to GND for phase compensation via the cap's ESR.
