The MAX1951ESA+T is an adjustable step-down (buck) switching regulator from Analog Devices, delivering up to 2 A of output current from a 2.6 V to 5.5 V input rail. Switching frequency is set internally between 800 kHz and 1.1 MHz — no external timing resistor. The 2 A continuous rating is the nominal output at the adjustable voltage set by the feedback divider; the minimum output is 0.8 V (the internal reference floor).
