LM1575 / LM2575 / LM2575HV SIMPLE SWITCHER 1A降压型稳压器 LM1575/LM2575/LM2575HV SIMPLE SWITCHER 1A Step-Down Voltage Regulator
DESCRIPON
The LM2575 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down buck switching regulator, capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable
output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed frequency oscillator.
