LT1129CQ-5#PBF is a kind of Linear voltage regulator, belonging to PMIC (power management ICs). A linear voltage regulator is basically an electrical circuit that tries to maintain a steady voltage from an electrical power source. It operates by comparing the input voltage to a reference voltage and adjusts the load current until the two voltages are equal.

To back up the information above, the LT1129CQ-5#PBF is a highly accurate, low power, single supply, 3A adjustable/fixed low dropout positive voltage regulator. It is ideal for use in a simple electronic circuit where overload and inrush current protection are not required. It is well suited for use in battery powered and/or low voltage applications.

The LT1129CQ-5#PBF can provide up to 3A of output current and is adjustable to outputs of 1.235V to 36V. It has a very low dropout voltage of only 0.7V at a full 3A load. It utilizes a startup cycle that limits the current to the device during start-up, making it ideal for use in applications with long power-up times. It also has a thermal shutdown as an additional protection feature.

The LT1129CQ-5#PBF has an internal voltage reference, enabling precise regulation at the output. It is available in standard 8-lead MSOP and SOIC packages and is RoHS compliant. The LT1129CQ-5#PBF has high accuracy, with an output voltage tolerance of ±0.6%. It can also operate over a wide temperature range, from -40°C to +125°C, making it suitable for use in industrial environments.

LT1129CQ-5#PBF is suitable for general purpose handheld devices, office equipment, telecommunications, low-voltage power supplies, PCMCIA cards, portable, and automotive applications. Typical applications of the LT1129CQ-5#PBF can be found in medical instrumentation, notebook computers, point of sale terminals, modems, and small scale solar array systems.

To summarize, the LT1129CQ-5#PBF is a Linear voltage regulator belonging to the PMIC family. It is highly accurate, low power, single power, 3A adjustable/fixed low dropout positive voltage regulator, with a startup cycle, as well as a thermal shutdown, to protect the device. It has a wide temperature range, making it suitable for industrial environments, and a voltage tolerance of ±0.6%. It can be used for general purpose handheld devices, office equipment, telecommunications, low-voltage power supplies, PCMCIA cards, and automotive applications.
