Ultra-Low Quiescent Current, 150mA µCap LDO Regulator

Micrel 

MIC5235

Adjustable Regulator Application

The MIC5235BM5 can be adjusted from 1.24V to 20V by

using two external resistors (Figure 1). The resistors set the

output voltage based on the following equation:

VOUT

Where VREF = 1.24V.

Feedback resistor R2 should be no larger than 300kΩ.
