LT1761MPS5-1.8#TRPBF - Low Noise, Low Dropout Voltage Regulator

The LT1761MPS5-1.8#TRPBF is a high-performance, low dropout voltage regulator from Analog Devices Inc., designed to deliver a fixed output of 1.8V with an output current up to 100mA. This component is part of the LT1761 series, known for its low noise operations and excellent power supply rejection ratio, making it ideal for sensitive RF and analog circuitry that requires a clean power source.

With its low quiescent current of 20μA (which reduces to

The device is designed with an internal PNP pass transistor that maintains a low dropout voltage of 300mV at full load, which is particularly beneficial during critical conditions when the input voltage is close to the output voltage. Additionally, the LT1761 series features a wide input voltage range from 1.8V to 20V, offering flexibility for various design requirements.

Another key feature of the LT1761MPS5-1.8#TRPBF is its low output noise, which can be further reduced with an optional external bypass capacitor. This makes it an excellent choice for precision applications such as high-end audio and reference voltage circuits. The device also includes overcurrent and overtemperature protection, enhancing its reliability and robustness in complex electronic systems.

This voltage regulator comes in a small, thermally efficient MSOP-8 package, which is suitable for space-constrained applications. The LT1761MPS5-1.8#TRPBF is also available in tape and reel packaging (denoted by the #TRPBF suffix), facilitating its use in automated manufacturing processes.

In summary, the LT1761MPS5-1.8#TRPBF from Analog Devices Inc. is a versatile, high-performance LDO voltage regulator that combines low noise, low quiescent current, and low dropout voltage, making it an excellent choice for a wide range of applications, including portable electronics, wireless devices, and precision instrumentation.
