The R5970AD is a step-down monolithic powerswitching regulator with a minimum switch currentlimit of 1.35 A so it is able to deliver up to 1 A DCcurrent to the load depending on the applicationconditions. The output voltage can be set from1.235 V to VIN.The device uses an internal P-channel DMOStransistor (with a typical RDS(on) of 250 m) asswitching element to minimize the size of theexternal components.An internal oscillator fixes the switching frequencyat 500 kHz. The large ambient temperature rangemakes it ideal for aerospace and defenseapplications. Pulse-by-pulse current limit with theinternal frequency modulation offers an effectiveconstant current short-circuit protection
General features– 1 A DC output current– Operating input voltage from 4 V to 36 V– 3.3 V / (± 2%) reference voltage– Large ambient temperature range:
