The AMS1117 is a series of low dropout voltage regulators which can provide up to 1A of output current. The AMS1117 is available in six fixed voltage, 1.2, 1.5, 1.8, 2.5, 3.3 and 5.0V. Additionally it is also available in adjustable version. On chip precision trimming adjusts the reference/ output voltage to within ± 2%. On-chip thermal limiting provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures. The AMS1117 series is available in SOT-223, TO- 252, SOT89 packages. A minimum of 10uF tantalum capacitor is required at the output to improve the transient response and stability.

The SL4275 is a monolithically integrated low-dropout fixed voltage regulator in a 5-pin TO package. Input voltages up to 55V are regulated to an output voltage VQ of 5.0V. The chip can drive 450mA load and has short circuit protection and over temperature protection. When the output voltage VQ is lower than the typical value of 4.65V, the RQ pin of the chip will generate a low-level reset signal, and the reset delay time can be set by the D pin delay capacitor.
