Low dropout CMOS voltage regulator family delivers up to 250 mA for output voltages of 2.5 V and higher, or 200 mA for lower output voltages. The regulator operates from a 2.3 V to 6.0 V input range and supports standard fixed outputs from 1.2 V to 5.0 V. Typical quiescent current is 1.6 µA, with typical dropout of 178 mV at 250 mA for a 2.8 V output. The output is stable with a 1 µF ceramic capacitor and includes short-circuit and overtemperature protection. Operating junction temperature range is -40°C to +125°C, and package options include SOT-23, SOT-89, TO-92, and 2x2 DFN-6 depending on the complete orderable suffix.
