H7533-H#

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

H7533-H# from Shanghai Siproin Microelectronics, 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 reference. Connect to the system single-point ground. Common return for both input and output current.
2 VIN power_in Regulator input supply. Operating range 4.75V to 40V (absolute max 45V). Bypass with a 10uF ceramic capacitor to GND close to the pin.
3 VOUT power_out Regulated 3.3V output (±2%), 100mA typical output current. Requires a 10uF output capacitor to GND for stability. Dropout is 600mV at 100mA.
