Overview
The LP2989IMM-3.3 is a linear Voltage Regulator made by Texas Instruments in a VSSOP-8-3mm package with 8 pins. -40℃~+125℃@(Tj) 1 16V 18uVrms 3.3V 500mA 60dB@(1kHz) 650mV@(500mA) Fixed Positive VSSOP-8-3mm Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:LP2989IMM-3.3_NOPB, from EasyEDA) and its footprint (Package_SO:VSSOP-8_3x3mm_P0.65mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C139368).
