The L4931CZ25-AP is a three-terminal adjustable linear voltage regulator capable of producing an output voltage between 1.2 V and 5 V and delivering up to 1 Amp of output current. This voltage regulator is well suited for many regulated power supply applications and provides a cost-effective alternative to using multiple linear series regulators. The L4931CZ25-AP is designed to allow the output voltage to be adjusted from a minimum of 1.2 V up to a maximum of 5 V. An onboard trim pot allows for the output voltage to be set to the desired range of operation.

This voltage regulator is particularly well suited for applications where high power conversion efficiency is needed and a tight output voltage control capability is desired. It is also suitable for applications where the input and output voltages are in the range typically associated with power supplies. The L4931CZ25-AP is a three-terminal adjustable linear voltage regulator that offers high efficiency, low noise and accurate output regulation. The on-board trim pot allows for the output voltage to be adjusted within the desired range of operation.

The L4931CZ25-AP application field and working principle is designed to provide a fast response, low-noise output voltage that can be set to any value within the range of 1.2 V and 5 V. This voltage regulator is designed to incorporate a wide range of temperature ranges , load conditions and line power sources. The L4931CZ25-AP is designed to maintain line regulation characteristics that are optimized for a wide range of input voltage variations. When the input voltage to the voltage regulator falls below the output voltage, the regulator automatically switches to constant current mode and the output voltage remains stable regardless of the input voltage.

The working principle of the L4931CZ25-AP is based on a technique called “negative feedback control”. This technique utilizes a sense resistor which monitors the voltage at the output of the regulator and provides feedback to the control circuit. This feedback is inversely proportional to the output voltage and causes the control circuit to adjust the output voltage until it is equal to the desired setpoint. The L4931CZ25-AP utilizes an on-board operational amplifier circuit to perform the feedback. The operational amplifier allows for the setpoint to be adjusted to different levels via a trim pot on the board.

The on-board operational amplifier works to compare the sense resistor voltage to the setpoint voltage and alters the output voltage level until these two voltages match. The control circuitry also monitors the output load current and the output voltage to ensure that the output voltage remains stable and within the specified range, even under varying load conditions. In addition, the control circuitry provides an adjustable soft-start feature to limit the inrush current.

The L4931CZ25-AP is a cost effective, highly efficient and robust voltage regulator. It offers low noise, adjustable output voltage and efficient regulation of output voltage and current. The adjustable output voltage and soft start features offer significant value and performance for many power supply and regulation applications. This device is well suited for use in a broad range of applications and provides a reliable, low cost solution for regulating input voltage to a wide range of output voltage requirements.
