Voltage references are an essential and fundamental part of any power management system. The LT1634CCZ-2.5#PBF is a low-dropout voltage reference that provides precision voltage shifts with very low power dissipation in a very small package. It is specifically designed to deliver consistent, low-noise operation in low power, portable applications. This makes it an ideal choice for a wide range of applications, such as battery-power management, digital regulators, and avionics and satellite systems.
The LT1634CCZ-2.5#PBF is an adjustable, low-dropout voltage reference and it is designed to operate from 1.2V to 8V with an output voltage range from 0V to 8V. It features a very low 200mV dropout voltage, a low operating current of only 15µA, and an operating temperature range of -40°C to 85°C. The LT1634CCZ-2.5#PBF also offers very high accuracy, with an output voltage tolerance of 0.3%.
To better understand the application field and working principle of the LT1634CCZ-2.5#PBF, the device is composed of two sections: an adjustable reference voltage generator and an output stage. The adjustable reference voltage generator is a band-gap reference driven by a constant current source. This reference voltage is then compared to the voltage on the external resistor divider formed by its MY/MG pins and M1/M2 pins. The voltage generated across the resistor divider is then used to adjust the reference voltage generated by the band-gap reference. The output stage is an operational amplifier connected as a voltage follower, which ensures the output voltage is equal to the reference voltage generated by the voltage generator.
The LT1634CCZ-2.5#PBF is ideal for use in portable and other applications that need precise, low-noise voltage shifts and low power consumption. Its simple, low-power design makes it an ideal solution for battery-powered devices, avionic & satellite systems, and digital regulators. Its low dropout voltage makes it well-suited for use in systems where the input voltage is close to the regulated output voltage. The low operating current, combined with its wide operating temperature range, makes it an excellent choice for many low power, portable electronics.
The LT1634CCZ-2.5#PBF provides precision voltage regulation, low power dissipation and a wide operating temperature range. This, combined with its adjustable output voltage, makes it an ideal choice for low-power applications that require precise, low-noise voltage shifts and stable operation. Additionally, its low operating current makes it ideal for use in battery-powered systems, digital regulators and avionics & satellite systems where power saving is an important consideration.
