Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The STMicroelectronics L4940D2T5 is a positive fixed 5V linear voltage regulator with a 1.5A output current capability. This device features a low dropout voltage of 0.9V at 1.5A and is designed for efficient power regulation in applications requiring stable voltage supply. Key protection features include over-temperature, reverse polarity, and short-circuit protection. The L4940D2T5 offers a high power supply rejection ratio (PSRR) of 68dB at 120Hz, ensuring minimal noise transfer to the output. Its operating temperature range is -40°C to 150°C. The component is housed in a D2PAK (TO-263-3, D2PAK (2 Leads + Tab), TO-263AB) surface-mount package and is supplied in tubes. This regulator is suitable for use in automotive systems, industrial controls, and power supplies.
