H7527-H#

Shanghai Siproin Microelectronics · Linear Voltage Regulators (LDO) · SOT-89-3

H7527-H# from Shanghai Siproin Microelectronics, in a SOT-89-3. 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 connection.
2 VIN power_in Supply voltage input; the datasheet gives an input range of 4.75 V to 40 V at IOUT=10mA and an absolute maximum rating of -0.3 V to 45 V.
3 VOUT power_out Regulated output; the output voltage is specified as VOUT×0.98 to VOUT×1.02 at IOUT=10mA, with maximum output current of 100mA (Typ.).
