The L4973D5.1-013TR is a step-down switching regulator capable of delivering up to 3.5 A at a fixed output voltage of 5.1 V with a tolerance of ±1%. It operates with an input voltage range from 8 V to 55 V and can also be configured for adjustable output voltages from 5.1 V to 50 V. The device features an adjustable switching frequency of up to 300 kHz, ensuring high efficiency and fast switching times due to its internal power D-MOS transistor with a typical RDS(on) of 0.15 Oc. Key protective features include pulse-by-pulse current limiting, hiccup mode for short circuit protection, thermal shutdown, and output over-voltage protection. The L4973D5.1-013TR also supports voltage feed forward regulation, soft-start functionality, and an inhibit mode for zero current consumption. It is available in a SO-20 package suitable for surface mount applications, making it versatile for various electronic designs.
