This is a very small boost regulator that generates 5 V from a voltage as low as 0.8 V and delivers 200 mA. It is perfect for powering small 5 V electronics projects from 1 to 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell. It is perfect for boosting battery with low voltage. The output current and output voltage depends on the input voltage. With a 0.8 V input, approximately 5 mA are available before the output voltage begins dropping. The full 200 mA output can be realized from input voltages over approximately 2.7 V. With low input voltages, the output voltage ripple is under 40 mV peak-to-peak; close to 5 V, the output ripple quickly climbs to 150 mV peak-to-peak. Therefore, adding capacitance from the output to ground is recommended for noise-sensitive applications with input voltages close to 5 V. Please refer to Pololu website for additional information.
