Linear Technology LT3021

The LT3021 is ideal for low input voltage to low output voltage applications, providing comparable electrical efﬁciency to that of a switching regulator. The LT3021 regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 3.3μF. The LT3021 is available as an adjustable output device with an output range down to the 200mV reference.
