Analog Devices LT1763CDE#PBF, 1 Low Dropout Voltage, Voltage Regulator 500mA, 1.22 → 20 V 12-Pin, DFN

Linear Technology LT1763 series are micropower low dropout regulators that can supply 500mA of output current with a dropout voltage of 300mV in addition they have a 1.22V reference voltage. The low noise LDO regulator has controlled quiescent current and will not rise in dropout. Over the bandwidth of 10 Hz to 100 kHz the LDO output noise can drop further with an external bypass capacitor. The Internal protection means reverse battery protection, reverse current protection, current limiting and thermal limiting. Typical applications include Cell phones, noise sensitive environments and battery powered systems.

LDO (Low Dropout) Linear Voltage Regulators, Linear Technology

Linear Technology Low Dropout Linear regulators (LDO) present very low dropout, line and load regulation and fast transient response. The positive, negative and multiple output LDO Linear regulators come in fixed or adjustable outputs. Some LDO+ devices have more features than the standard linear regulators; some can monitor the voltage, current and temperature. They also feature program current limit, active output discharge or even control an upstream supply powering the LDO.

Fast Transient response time
Wide Input Voltage range: 0.9V to 80V
Output Currents from 100mA to 7.5A
