LT1129CT-3.3#06PBF

The LT1129CT- 3.3#06PBF is a voltage regulator belonging to the Linear category of PMIC (Power Management Integrated Circuits). It is a low drop-out (LDO) three-terminal voltage regulator, ideal for applications requiring improved transient response, low noise and improved line regulation performance. It offers an excellent power supply rejection ratio (PSRR), high output current capability, and extremely low quiescent current.

The LT1129CT- 3.3#06PBF is a low noise linear voltage regulator that can provide up to 200mA of regulated output current with a dropout voltage typically less than 500mV. It offers ultra-high PSRR performance and fast transient response due to the wide bandwidth of linear output amplifier. It also provides excellent line regulation over a wide input voltage range.

The LT1129CT-3.3#06PBF is used in automotive, consumer electronics, telecom and communication, industrial, medical, and portable applications. It is suitable for applications that require low dropout voltage and high power supply rejection ratio. In automotive applications, it is used to provide regulated output from an unregulated supply, enabling enhanced performance in noise-sensitive systems. It is also used in consumer electronics for regulating the output voltage for low noise operation.

The LT1129CT-3.3#06PBF works on the principle of voltage regulation by controlling the output voltage based on the voltage at its sense pin. It has an internal bandgap voltage reference which provides a stable voltage to the output. The output of the device is compared to a reference voltage and the difference is then amplified by an error amplifier. The output of the error amplifier controls the pass PMOS transistor which adjusts the output voltage. Upon a change in the input voltage or load current, the output voltage is modulated to maintain the desired output voltage.

The LT1129CT-3.3#06PBF includes various built-in safety mechanisms such as over-temperature protection, thermal shutdown, over-current protection, and reverse current protection. It also includes an internal soft-start circuit to limit the inrush current during turn-on. The device also includes an enable pin that can be used to put the device in either shutdown or low-power mode.

The LT1129CT- 3.3#06PBF has been designed for use in a wide range of electronic applications with improved efficiency, fast response time and low noise operation. It is a reliable and cost-effective solution for the regulation of voltage in power systems requiring low dropout and high power supply rejection ratio.
