![]() In-built current limit protection & thermal shutdown This voltage regulator provides permanent o/p voltages like 3.3V, 5V, 12V & 15V. This voltage regulator includes fixed frequency voltage with 52kHz of the internal oscillator of frequency. Senses the regulated output voltage to complete the feedback loopĮnable pin, should be grounded for normal operation In order to minimize coupling with sensitive circuits, the copper area of the PCB connected to this pin must be kept to a minimum. The voltage on this pin is switched between approximately (+V IN -V SAT ) and approximately -0.5 V, and the duty cycle is V OUT /V IN. There must be a suitable input bypass capacitor on this pin to minimize voltage transients and to supply the switching currents required by the regulator. This is the positive input power of the IC switching regulator. ![]() This pin is provided with the feedback voltage based on which the output is regulatedĬonnect to the ground to activate the regulator or connect to Vcc to disable the regulator. The regulated output can be obtained through this pin The voltage which has to be regulated is provided as input to this pin
