The LM2575-5.0WU from Microchip Technology is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. This fixed 5V version provides a 1A output current with excellent line and load regulation. It operates at a fixed frequency of 52kHz, simplifying power supply design by requiring a minimum number of external components and including internal frequency compensation.
This regulator is suitable for surface mount applications, utilizing a TO-263-5 package. It offers a wide input voltage range from 4V to 40V and a wide output voltage range from 1.23V to 37V. The device features thermal shutdown and cycle-by-cycle current limiting for protection under fault conditions. Its high efficiency makes it a replacement for linear regulators, often eliminating the need for a heat sink.
Key electrical specifications include a 1A guaranteed output current and a 52kHz internal oscillator frequency. The fixed output voltage is guaranteed to ±3% tolerance within specified conditions. External shutdown is supported, with a typical standby current of less than 200µA.
