3 Description
The LMZ21700 SIMPLE SWITCHER^® Nano Module
is an easy-to-use step-down DC-DC solution capable
of driving up to 650 mA load in space-constrained
applications. Only an input capacitor, an output
capacitor, a softstart capacitor, and two resistors are
required for basic operation.
Quick links to typical applications: V_OUT = 1.2 V, V_OUT
= 1.8 V, V_OUT = 2.5 V, V_OUT = 3.3 V, V_OUT = 5.0 V
