LM1086IT-2.85/NOPB

Introduction

The LM1086IT-2.85/NOPB is a low dropout two-terminal adjustable voltage regulator with an ultra-low quiescent current. It is designed for applications that require high-voltage precision regulation, like post-regulators for switchmode converters or supplies. It is part of the family of low dropout regulators (LDOs) by Texas Instruments, having its main application in active power management systems and convergence avoiding circuits. Such circuits can be used in systems with power-sensitive applications such as mobile phones, in-car infotainment systems, cameras and industrial applications.

Application Field of the LM1086IT-2.85/NOPB

The LM1086IT-2.85/NOPB is a two-terminal low dropout voltage regulator that is designed for use in active power management systems and convergences avoiding circuits. These circuits that require high-voltage precision regulation and a very low quiescent current. It can used in applications such as post-regulators for switchmode converters or supplies, e.g. in-car infotainment systems, industrial and mobile phones. The regulator is particularly suitable for low-power, voltage sensitive applications.

The LM1086IT-2.85/NOPB includes several unique features that ensure high performance, including a wide operating range, low dropout voltage and low temperature coefficient. It also has a wide operating temperature range of up to -40°C to +85°C. The dropout voltage from the LM1086IT-2.85/NOPB is typically only 120mV at a load current of 10mA with a maximum input voltage of 12V.

Working Principle of the LM1086IT-2.85/NOPB

The LM1086IT-2.85/NOPB is an adjustable two-terminal linear voltage regulator. It uses a pass-transistor type of regulation, in which the output voltage remains constant. The regulator works by comparing the voltage of the input against the voltage at the output, then using negative feedback to reduce the voltage difference and thus regulate the output voltage. The output voltage can be adjusted with a trimmer or external resistors to a wide range of values.

The LM1086IT-2.85/NOPB has an adjustable output voltage range of up to 17V, and can withstand a maximum input voltage of 12V. Other features include an enable control pin and thermal shutdown. The enable pin enables the regulator to be switched on and off remotely, making it useful for battery powered applications. The thermal shutdown provides additional protection in case of thermal overload.
