HG7533M3-1

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

HG7533M3-1 from HGSEMI, in a SOT-23. 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 reference. Return path for both quiescent current and load current; tie directly to the system ground plane.
2 VIN power_in Unregulated supply input pin. Accepts up to 36 V absolute maximum (VDD = -0.3 V to +36 V). Bypass close to the pin to GND; must be at least VOUT + Vdropout above the target output.
3 VOUT power_out Regulated 3.3 V output pin (3.234 V min / 3.300 V typ / 3.366 V max at VIN = VOUT+2 V, IOUT = 10 mA). Delivers up to 100 mA (70 mA min). Requires an output capacitor to ground for stability.
