LDR2533BPT-R is a low dropout linear voltage regulator that offers reliable and robust performance for regulated power supply applications. Its wide output voltage range is adjustable from 0.8 V to 25 V, and the outputs can be genetically adjusted. It has a wide input voltage range of 18 V to 35 V.
The LDR2533BPT-R is designed to provide a regulated output voltage when supplied with an input voltage that is slightly higher than the output voltage. This circuit utilizes an on-board precision power transistor and NMOSFET technology which makes its operations more stable, efficient and cost-effective. The integrated technology also provides low noise, low dropout, low temperature coefficient and overvoltage protection. The device is also capable of providing continuous current up to a maximum of 800 mA.
The LDR2533BPT-R is typically used in a wide variety of applications such as 5V logic-level voltage regulation, 5V microprocessor power supplies, supply voltage tracking, line voltage application, current booster, and other power management applications. It is also an excellent choice for battery management applications such as battery power charging and stabilization.
The working principle of the LDR2533BPT-R is based on the multifunctional approach provided by its on-board integrated circuit. The device is equipped with an adjustable control terminal which helps to determine the regulation voltage or the output voltage. The input voltage is applied to the integrated circuit and through an internal circuitry it is then compared against an adjustable reference voltage. An error amplifier and a feedback network then help to adjust the output voltage to the requested value. The on-board precision power transistor then delivers the regulated output voltage.
The LDR2533BPT-R includes an extra protection circuitry which helps to protect the device from overvoltage, reverse polarity, over temperature and short circuit. Its excellent temperature coefficient helps to suppress the output voltage deviation due to temperature variations. To summarize, the LDR2533BPT-R is an ideal choice for applications where reliability, accuracy and low power consumption are needed.
