LDO compensation strategy based on current buffer/amplifiers
In this communication, we propose a compensation procedure for LDO regulators which exploits both a current/buffer amplifier Miller compensation and a standard Miller compensation. The analysis shows how to design the compensation network in order to guarantee the stability for all the loading conditions. The results are then used to design a LDO regulator which is stable for a load current range of 4 orders of magnitude (from 10 muA to 100 mA) without requiring an external off-chip capacitor with ESR. Simulations in good agreement with the theoretical results are also shown.
