It is capable of supplying 2-A to loads with an output voltage as low as 0.8 V. Dual N-channel synchronous MOSFET switches allow a low component count, thus reducing complexity and minimizing board size. Different from most other COT regulators, the LMR24220 does not rely on output capacitor ESR for s...
