Overview
The LR7133-M is a linear Voltage Regulator made by LR in a SOT-89-3 package with 3 pins. SOT-89-3 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-89-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2844947).
