Introduction

AI Translation

The series are low noise, low dropout linear regulators. The devices supply 1.1A of output current with a 310mV typical dropout voltage. Operating quiescent current is 500µA for the adjustable version, reducing to <1µA in shutdown. Quiescent current is well controlled; it does not rise in dropout as with many other regulators. The regulators have very low output noise which makes them ideal for sensitive RF and DSP supply applications. Output voltage ranges from 1.20V to 19.5V. The regulators are stable with output capacitors as low as 10µF. Internal protection circuitry includes reverse-battery protection, current limiting with foldback, thermal limiting and reverse-current protection. The series are available in fixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V, and as an adjustable device with a 1.20V reference voltage. The package offerings include the 5-lead TO-220, 5-lead DD-Pak as well as the thermally enhanced 8-lead MSOP and low profile (0.75mm) 8-lead 3mm × 3mm DFN.
