LR7527-M

LR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

LR7527-M from LR, 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 VSS power_in Ground pin (labelled VSS in the pin assignment, GND in the block diagram), reference for all voltage values.
2 VIN power_in Regulator input supply, operating up to 24V (absolute maximum 32V), with a bypass capacitor connected close to the pin.
3 VOUT power_out Fixed 2.7V regulated output delivering 100mA with ±2% accuracy, with a 1-10uF output capacitor recommended and short-circuit current limited to 20mA.
