Due to reducing the number of external component, the board space can be saved easily.
The external shutdown function can be controlled by logic level and then come into standby mode.
The internal compensation makes feedback control have good line and load regulation without external design.
Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch.
The LSP3127 series operates at a switching frequency of 52 KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.
Other features include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions, and ±15% on the oscillator frequency.
The output version included fixed 3.
3V, 5V, 12V, and an adjustable type.
The package is available in a standard SOP8-EP package.
