LT3089ER#TRPBF is a low dropout (LDO) linear regulator that belongs to the Power Management Integrated Circuit (PMIC) family. It is one of the most advanced Linear Voltage Regulators (LVR) available in the market today. The LT3089ER#TRPBF provides a very high power supply rejection ratio (PSRR) and ultra-low dropout voltage (LDO). It is designed for use in portable and industrial applications that require low-noise and high current output power.The LT3089ER#TRPBF is a fixed-output, low-noise, low-dropout linear regulator that operates with input voltages up to 12V. It can provide up to 1.5A of output current with an output voltage accuracy of 0.2%. The device features a low dropout voltage of only 30mV at 1A of output current and an internal power-on reset (POR) circuit. It also has an integrated thermal overload protection. The LT3089ER#TRPBF is available in a small 3-pin TO-220 package.The LT3089ER#TRPBF is designed to improve power performance in a wide variety of applications, including battery-backed systems; data logging and communication systems; embedded system controllers and PC/C devices; and power management modules. In addition, it can also be used in automotive, industrial and medical applications.The LT3089ER#TRPBF linear regulator operates in a very simple way. It is powered by an input voltage, typically 12V or higher, and then provides an output voltage that is held to the desired voltage level. This is accomplished through a feedback loop mechanism, with the positive input of the comparator being the input voltage, and the negative input being the output voltage. This allows the PWM controller to make adjustments to the internal power MOSFET to vary the output voltage to match the input voltage. The LT3089ER#TRPBF features a low dropout voltage of only 30mV at 1A output current, typically 60mV at typical output current. This low dropout voltage helps reduce heat dissipation and improves power efficiency. In addition, the LT3089ER#TRPBF features an integrated power-on reset (POR) circuit, protecting against any unprotected power up conditions. The LT3089ER#TRPBF also features an overload protection and thermal overload protection, providing additional safety and reliability. The LT3089ER#TRPBF linear regulator is designed to provide high power supply rejection ratio (PSRR) performance, allowing it to reject line irregularities and maintain a stable output voltage. The PSRR of the LT3089ER#TRPBF is typically 100 dB at 1 kHz and 65 dB at 20 kHz. This high PSRR performance helps to improve the overall immunity of the system to electromagnetic interference and power fluctuations.In summary, the LT3089ER#TRPBF is an advanced linear regulator that offers a very low dropout voltage, high power supply rejection ratio, and an integrated power-on reset (POR) circuit with thermal overload protection. It is designed for use in portable and industrial applications that require low-noise and high current output power. The LT3089ER#TRPBF is a great choice for powering a wide range of industrial, automotive, medical and consumer applications.
