Ic LM2576HVS-5 TO-263 SMD LM2576 HV 5V StepDown Switching LM 2576

General DESCRIPTION
The LM2576HV series of regulators are monolithic integrated circuits that
Provide all the active functions for a step-down (buck) switching regulator,
Devices are available in fixed output voltages of 3.3V, 5V, 12V, and an
Adjustable output version.
Available in a standard 5-lead TO-220 package, 5-lead TO-263 surface
Mount package and SOP-8 package.
External shutdown is included, featuring typically 30 ?A standby current.
The output switch includes cycle-by-cycle current limiting, as well as
Thermal shutdown, and protection from output short for full protection
Under fault conditions.
Features FEATURES
? 3.3v, 5V, 12V, and adjustable output versions
