Introduction
The LT1086CM#PBF is a low noise, low dropout, low quiescent current monolithic linear regulator from Linear Technology. It is a three-terminal series regulator that employs a PMOS pass transitor. This PMIC-Voltage Regulator-Linear is capable of providing an output current up to 2A with an output voltage of 0.1V to 38V. It has an adjustable current-limit feature that allows it to automatically protect the receiver circuit when the output current exceeds the set current-limit value.Specifications
The LT1086CM#PBF has following specifications:- Input Voltage range: 4.5V to 40V
- Output Voltage range: 0.1V to 38V
- Power Dissipation: 1.1W
- Max Output Current: 2A
- Output Voltage Adjustment Range: 5mV to 50mV (typical)
- Current Limit: Adjustable from 10mA To 2A (typical)
- Dropout Voltage at 1A: 0.3V @ Typ Temperature
- Quiescent Current: 30uA @ Typ Temperature
- Line Regulation: 0.02%/V
- Load Regulation: 0.1%
Application
The LT1086CM#PBF is mainly used in the applications where precision output voltage and low noise operation is required. These applications include:- Battery-powered circuits
- Digital system power supply
- Audio amplifier circuits
- Portable instrumentation systems
- Mobile communication equipment
- Telecommunication systems
Working Principle
The LT1086CM#PBF uses a PMOS pass transistor to regulate the output voltage. The input voltage is regulated by the pass transistor and output voltage is compared to an internal reference voltage. When the output voltage is lower than the reference voltage, the pass transistor is turned on and current flows from the input to the output. As the current increases, the pass transistor draws more power from the input and the output voltage rises until it reaches its target value. When the output voltage is higher than the set value, the pass transistor is turned off, limiting the amount of current that can flow from the input to the output. This ensures the maximum output current is not exceeded and prevents the regulator from entering a “crowbar” or “short circuit” condition.Conclusion
The LT1086CM#PBF is a low noise, low dropout and low quiescent current monolithic linear regulator. It has an adjustable current-limit feature that allows it to automatically protect the receiver circuit when the output current exceeds the set current-limit value. This PMIC-Voltage Regulator-Linear is mainly used in the applications where precision output voltage and low noise operation is required.The specific data is subject to PDF, and the above content is for reference
