LD1086V Application Field and Working Principle

LD1086V is a high current, three-terminal adjustable, positive voltage regulator from STMicroelectronics. It belongs to the category of linear voltage regulators, and belongs to the Power Management Integrity Circuits (PMIC) family. It is widely used in power supplies need higher power, especially in high current applications due to its very low on resistance and high thermal performance.

Features of LD1086V

The LD1086V features good maximum output current and voltage range, good line and load regulation, adjustable output voltage and temperature stability, and low draw current over temperature. It also features low dropout voltage and very low operating current. Furthermore, it has thermal shutdown and short-circuit protection.

Applications

LD1086V can be used in a wide range of applications such as Power Management, Power Supply, and Voltage Regulation. It is widely used in active PFC circuits where high power currents are needed and in UPS or industrial power supplies and medical equipment. It is also widely used in AC/DC converter circuits and for input power for processor systems. It is widely used in various devices such as cellular phones and other digital products, with high current load.

Architecture and Working Principle

The LD1086V is a voltage regulator that can be adjusted from 1.2V to 37V, with a minimum input-output voltage differential of 2.5V. This device uses a MOSFET transistor as a main switch for power conversion. When the voltage on the output drops below the reference voltage, the MOSFET will automatically turn on to increase the output voltage. When the voltage on the output is greater than the reference voltage, the MOSFET will turn off, which will decrease the output voltage. This process is repeated in order to keep the output voltage stable.

LD1086V also features additional functions such as thermal shutdown protection, current limiting and reverse-battery protection. The thermal-shutdown feature will automatically shut down the LD1086V when the temperature rises above its normal operating temperature. The current limiting feature is used to limit the current at an adjustable level, depending on the specific application. The reverse-battery protection feature is used to protect the device from reverse voltage spikes.

Package and Pin Out

The LD1086V is available in two packages: TO-92 and D2PAK. The D2PAK is a Dual Inline Package with three terminals for easy connection. The TO-92 package is a three pin package, with one pin for the input voltage, one for ground and one for the output voltage. Both packages have four different versions: a 5A version, a 7A version, a 10A version and a 12A version.

The pinout of the LD1086V is as follows: the input is the first pin and goes to the positive terminal of the power supply; the second pin is the ground, or negative terminal of the power supply; and the third pin is the output voltage pin.

Conclusion

LD1086V is a high current, three-terminal adjustable, positive voltage regulator from STMicroelectronics. It is a 3-terminal adjustable positive voltage regulator used in many applications. It features good maximum output current and voltage range, adjustable output voltage and temperature stability, and low draw current over temperature. It is available in two packages: TO-92 and D2PAK. LD1086V is used in a wide range of applications such as Power Management, Power Supply, and Voltage Regulation and is widely used in active PFC circuits, UPS or industrial power supplies, medical equipment, and AC/DC converter circuits.
