Features

The LT6656ACS6-1.25#TRPBF is a low-dropout and low-noise voltage regulator that integrates three independent voltage references and up to 30 mA of output current into one small package. It offers the following features:- Output voltage range from 0.5 – 6.5 V- Low dropout of 0.175 V (typical) at 1 mA of load current- Low output noise- Fast response to load transients- Over-temperature and over-current protection- Internally trimmed voltage- Available in a variety of package options

Working Principle

The LT6656ACS6-1.25#TRPBF operates on the principle of feedback regulation. The voltage reference is created by comparing the output voltage to an internally set reference voltage. The reference voltage is trim-set at the factory, and is selectable for different output voltage ranges. The output voltage is regulated by controlling the current through an error amplifier, based on the difference between the output voltage and the reference voltage. An internal pass transistor is used to provide the output current. The pass transistor is controlled by the error amplifier and is used to provide the output voltage. The voltage reference and error amplifier are controlled by the feedback signal of the output voltage.The device is available in a variety of packages for easy implementation. It is supplied with a 2.5V reference voltage and the output voltage can be adjusted within a 0.5V- 6.5V range. The device also has an over-temperature protection which helps prevent overheating and saves cost by providing guaranteed performance even in extreme conditions.
