FAQs

What is LT1086CM?

The LT1086CM is a low dropout voltage regulator manufactured by Linear Technology (now part of Analog Devices). It is designed to provide a stable output voltage with low dropout voltage, making it suitable for applications requiring precise voltage regulation.

How Does LT1086CM Work?

The LT1086CM regulates the output voltage by comparing a reference voltage with the feedback voltage derived from the output. It adjusts the pass transistor to maintain a constant output voltage even when the input voltage varies. The low dropout feature enables the regulator to operate with minimal headroom voltage, making it efficient in various power supply applications.

How Many Pins does LT1086CM have and What are the Functions of the Pinout Configuration?

The LT1086CM is available in an 8-lead metal can package. The pinout configuration includes:

IN: Input voltage pin.
OUT: Output voltage pin.
ADJ: Adjustable pin for setting output voltage.
GND: Ground pin.

What are the Pros and Cons of LT1086CM?

Pros:

Low Dropout Voltage: Enables efficient operation even with small voltage differentials.
