AMS1117-3.3 SOT-89 Voltage Regulator Low Drop Out +3.3V – 1A is a fixed low dropout voltage regulator with a dropout voltage of 1.3V at 1000mA of load current. It offers current limiting and thermal shutdown and includes a Zener bandgap reference to assure output voltage accuracy to within ±1%.
Low-dropout (LDO) regulators work similarly to all linear voltage regulators. The main difference between LDO and non-LDO regulators is their schematic topology. Instead of an emitter follower topology, low-dropout regulators use an open collector or open drain topology. In this topology, you may quickly drive the transistors into saturation with the voltages available to the regulator.
This allows the voltage to drop from the unregulated voltage to the regulated voltage as low as the saturation voltage across the transistor.
If a bipolar transistor is used instead of a field-effect transistor or JFET, you may lose significant additional power to control it. In contrast, non-LDO regulators take that power from the voltage drop itself.
