The AB version offers +\/-2% accuracy for tight regulation on 24V industrial rails. Input up to 40V with 2V typical dropout at 350mA. Internal current limiting, thermal shutdown, and SOA protection make it essentially indestructible. The DPAK package provides surface-mount with tab for heatsinking.","working_principle":"The L78M24ABDT-TR uses a series-pass NPN transistor in emitter-follower configuration controlled by a feedback amplifier comparing the output voltage with a temperature-compensated bandgap reference. Current limiting monitors output current via internal sense resistor. Thermal shutdown disables the pass transistor at approximately 150C junction. SOA protection reduces current limit as input-output differential increases.","pin_description":"
