LR6375A33P

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

LR6375A33P from LRC, 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 VSS power_in Ground / negative supply return. All device voltages are referenced to this network ground terminal.
2 VIN power_in Unregulated power input. Recommended supply range 2.5 V to 36 V (absolute maximum −0.3 V to +40 V). Bypass to VSS with a 1 µF ceramic or tantalum capacitor close to the pin; a 3 Ω series resistor is recommended with X5R MLCC to suppress start-up transients.
3 VOUT power_out Regulated 3.3 V output (LR6375A33: '33' code = 3.3 V), up to 250 mA. Requires a 1 µF tantalum (or ceramic for improved transient response) capacitor to VSS close to the pin for loop stability. DC accuracy ±2 % typical (±1 % option), 400 mV typical dropout at 100 mA. Internal current limit ~350 mA and short-circuit fold-back ~25 mA when VOUT = VSS.
