LT1965EDD#PBF Beschreibung

The LT1965EDD#PBF series are low-noise, low-dropout linear regulators. The devices supply 1.1A of output current with a 310mV typical dropout voltage. The quiescent operating current is 500μA for the adjustable version, reducing to <1μA in shutdown. Quiescent current is well controlled; it does not rise in dropout like many other regulators. The LT1965EDD#PBF 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 LT1965EDD#PBF 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 LT1965EDD#PBF series are available in fixed output voltages of 1.5V, 1.8V, 2.5V, and 3.3V and as an adjustable device with a 1.20V reference voltage. The package offerings include the 5-lead TO-220 and 5-lead DD-Pak, the thermally enhanced 8-lead MSOP, and low profile (0.75mm) 8-lead 3mm × 3mm DFN.
