LT1763CS8-3.3#TRPBF is a linear voltage regulator by Analog Devices Inc (ADI) which provides adjustable output voltage from 1.21V to 24V — it is a feature in the PMIC (Power Management IC) voltage regulators family. This device is based on a three-term Linear Regulator topology, specifically designed to help provide regulated output voltage for heavy-duty non-isolated switching power supplies — for use in applications such as automotive, communications, consumer and industrial.

The key features of the LT1763CS8-3.3#TRPBF linear voltage regulator include an output voltage adjustable from 1.21V up to 24V, an operating current specification of 12A, an adjustable reference current of 3.75mA, an adjustable current limit of 15A, a maximum output current of 25A, a Temperature Derating of 4.0A/°C and a Temperature Range of –40 °C to 125 °C.

The LT1763CS8-3.3#TRPBF can also provide transient response performance equivalent to many faster devices due to its very low parasitic values — this advantage comes from the use of components that are optimized for power dissipation in current-limited applications.

Working Principle

The LT1763CS8-3.3#TRPBF consists of a low dropout linear voltage regulator, a current-sense amplifier and an adjustable current source. The regulator is configured in a three-term linear topology with a fixed output voltage. The voltage set-point is determined by connecting a resistor divider between the ADJ and GND pins, allowing for either a fixed output voltage or for the adjustable output range of 1.21V to 24V.

The current-sense amplifier measures the current flowing through the load, allowing the LT1763CS8-3.3#TRPBF to provide over-current protection by responding to changes in output current with an appropriate shut-down signal. The current source allows for an adjustable current limit on the output, while at the same time providing a constant output current over the full range of the output voltage.

The linear voltage regulator also contains an active loop compensation network which helps limit the output voltage ripple and improve overall system performance. The LT1763CS8-3.3#TRPBF also helps provide power supply stability by preventing oscillations, minimizing the number of external components required.
