3 Description
The LMZ21701 SIMPLE SWITCHER® Nano Module
is an easy-to-use step-down DC-DC solution capable
of driving up to 1000 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: VOUT = 1.2 V, VOUT
= 1.8 V, VOUT = 2.5 V, VOUT = 3.3 V, VOUT = 5.0 V
