LT1965HT#PBF is a versatile high performance Monolithic low dropout positive voltage regulator. This product is part of Analog Devices voltage regulator family and is categorized under PMIC - Voltage Regulators - Linear. This product is suitably designed for those applications that involve a low input voltage and high current capability. This product can deliver maximum output current up to 4.0A and provide very low dropout voltage even at high current because it includes a large on-chip power MOSFET.

The LT1965HT#PBF is available in an 8-ball HSOP-8 (1mm) surface-mount package which makes it well-suited for portable applications. It showcases an excellent load-transient response with a fast turnon time. The IC includes protection features such as reverse current protection, current limit, thermal shutdown protection. This product also includes an adjustable version as LT1965HV#PBF and a fixed version available as LT1965#PBF.

The working principle of the LT1965HT#PBF is quite simple and well understood. It comes with a design architecture of an error amplifier connected in feedback control mode to a supply ground. When a voltage is applied to the input, the error amplifier compares the difference between the output voltage and the reference voltage of the regulator. If there is any disparity, the error amplifier adjusts its output to balance the input and output voltages. This drives the MOSFET gate that effectively controls the voltage at the regulator’s output.

The LT1965HT#PBF is suitable for applications such as low-voltage logic systems, automotive end-of-life, cellular phone standby power, portable hand-held battery charging and powering, low-power audio amplifiers, low-noise operation, remote and local power supplies, and many other peripheral systems or equipment.

To conclude, the LT1965HT#PBF is an excellent choice for those applications that require a low input voltage and high current supplying capability. This product offers high performance, low dropout voltage, small package size, protection features and a very fast turn-on time. It also suits a diverse range of applications ranging from low-voltage logic systems to remote and local power supplies.
