... Equipped with a logic-compatible enable pin, the MIC5319 can be put into a zero-off-mode current state, drawing no current when disabled. The MIC5319 is a µCap design operating with very small ceramic output capacitors for stability, thereby reducing required board space and component cost. The MIC5319 is available in fixed-output voltages and adjust- able output voltages in the super-compact 2mm x 2mm MLF leadless package and thin SOT-23-5 package ...

... Adjustable Regulator Application Adjustable regulators use the ratio of two resistors to multiply the reference voltage to produce the desired output voltage. The MIC5319 can be adjusted from 1.25V to 5.5V by using two external resistors (Figure 1). The resistors set the output voltage based on the following equation: R1 ...
