The LT1965IDD-3.3#PBF LDO Voltage Regulator manufactured by Analog Devices is a high current, low noise, low dropout (LDO) regulator specifically designed for powering audio and communication circuits. It features a maximum load current of 1.1A and a dropout voltage (Vout - Vin) of typically 400mV. The input voltage range is 3.1V to 24V and the output range is 3.2V to 16V, adjustable with an external resistor. It has an output noise voltage of just 300µVrms, eliminating any need for additional noise suppression components. The internal PMOS pass transistor enables high efficiency operation without the need for an external compensation capacitor, enabling a smaller footprint and lower bill of materials. The LT1965IDD-3.3#PBF is supplied in a space saving SOT-223 package, making it an ideal choice for a wide variety of portable, industrial, and consumer applications.
