DESCRIPTION The LT? 1764A is a low dropout regulator optimized for fast transient response. The device is capable of supplying 3A of output current with a dropout voltage of 340mV. Operating quiescent current is 1mA, dropping to < 1μA in shutdown. Quiescent current is well controlled; it does not rise in dropout as it does with many other regulators. In addition to fast transient response, the LT1764A has very low output voltage noise which makes the device ideal for sensitive RF supply applications. FEATURES ■ Optimized for Fast Transient Response ■ Output Current: 3A ■ Dropout Voltage: 340mV at 3A ■ Low Noise: 40μVRMS(10Hz to 100kHz) ■ 1mA Quiescent Current ■ Wide Input Voltage Range: 2.7V to 20V ■ No Protection Diodes Needed ■ Controlled Quiescent Current in Dropout ■ Fixed Output Voltages: 1.5V, 1.8V, 2.5V, 3.3V ■ Adjustable Output from 1.21V to 20V ■ <1μA Quiescent Current in Shutdown ■ Stable with 10μF Output Capacitor* ■ Stable with Ceramic Capacitors* ■ Reverse Battery Protection ■ No Reverse Current ■ Thermal Limiting APPLICATIONS ■ 3.3V to 2.5V Logic Power Supply ■ Post Regulator for Switching Supplies |
