FAQs

What is AMS1085CD?

The AMS1085CD is a low dropout (LDO) voltage regulator designed by Advanced Monolithic Systems. It is ideal for applications requiring a stable and adjustable output voltage with minimal dropout voltage, such as power management in automotive, industrial, and consumer electronics.

How Does AMS1085CD Work?

The AMS1085CD operates as a voltage regulator, providing a stable output voltage even when the input voltage fluctuates. It uses an internal reference voltage and feedback control to maintain the desired output voltage, and its low dropout voltage allows it to regulate the output even when the input voltage is only slightly higher than the output voltage.

How Many Pins does AMS1085CD have and What are the Functions of the Pinout Configuration?

The AMS1085CD is housed in a 3-pin TO-252 package. The pinout configuration includes:

ADJ: Adjustable output pin.
VOUT: Regulated output voltage pin.
VIN: Input voltage pin.

What are the Pros and Cons of AMS1085CD?

Pros:

Low Dropout Voltage: Maintains regulation with minimal input-to-output voltage differential.
Adjustable Output: Allows flexibility in setting the output voltage as per application requirements.
Thermal Overload Protection: Includes protection against excessive heat, enhancing system reliability.
Simple Design: Requires minimal external components for stable operation.

Cons:

Heat Dissipation: May require a heatsink for high power dissipation applications.
Current Limiting: Has a maximum output current limit that needs to be considered in high-load scenarios.

Are There Any Equivalents/Alternatives to AMS1085CD for Recommendation?

The LM1085 from Texas Instruments is an equivalent alternative to the AMS1085CD.
Alternatives to the AMS1085CD include the L4940 from STMicroelectronics and the MIC2940 from Microchip Technology.
