LT3029IDE#PBF

LT3029IDE#PBF Application Field and Working Principle

LT3029IDE#PBF is a high-precision, low-noise, constant-current linear regulator for a wide range of applications. It provides accurate, noise-free power with an ultra-low quiescent current of just 6.6 µA. Its robust design makes it a great choice for powering sensitive and temperature-critical applications.

LT3029IDE#PBF works by setting the drain current of a PMOS transistor to a desired level which is determined by the input voltage and the feedback resistor. The feedback resistor acts as a voltage divider, allowing the voltage across the resistor to drop until it reaches the internal reference voltage of the LT3029IDE#PBF. When the voltage across the feedback resistor reaches the reference voltage, the internal PMOS transistor is set to the required drain current, providing a constant current source or drain. The voltage regulator circuit has various blocks and operations, allowing the rail voltage to stay constant despite variations in the input voltage.

Applications

LT3029IDE#PBF is suitable for a wide range of applications such as automotive, industrial and medical. Applications include powering low-current, high-precision sensor nodes, ASIC compensation voltage supplies, laser sub-system power supplies, photodiode bias circuits and amplifier supply voltages. Additionally, the regulator is heavily shielded from variations in ambient temperature, making it capable of powering temperature-critical applications.
