The AMS1117CD-ADJ from UMW is a robust adjustable linear regulator delivering up to 1A of output current. With an output range from 1.25V to 10.8V, it offers design flexibility for various low-power applications. Its low dropout voltage of 1.3V ensures efficient operation even with small input-to-output headroom. Housed in a TO-252 (DPAK) package, it provides excellent thermal performance for continuous load operation.
- High Output Current: 1A capability supports a wide range of loads, from microcontrollers to small actuators.
- Adjustable Output: Set any voltage from 1.25V to 10.8V with just two resistors, maximizing design versatility.
- Excellent Ripple Rejection: 75dB PSRR at 120Hz ensures clean, stable power for sensitive analog circuits.
- Low Dropout: 1.3V dropout allows operation from batteries or slightly higher rails, improving efficiency.
Adjustable Power Supply for Microcontrollers
Use the AMS1117CD-ADJ to create a precise, adjustable rail (e.g., 3.3V or 5V) for MCU boards. Its 1A current capability comfortably powers logic, sensors, and communication modules while maintaining low dropout.
Battery-Powered Devices
With a low dropout of 1.3V, this LDO efficiently regulates from a 2-cell Li-ion or 3-cell alkaline stack down to a stable adjustable voltage, extending usable battery life.
FPGA and DSP Core Supplies
FPGAs and DSPs often require a dedicated, noise-sensitive core voltage. The AMS1117CD-ADJ provides a clean, adjustable output with 75dB PSRR at 120Hz, reducing ripple from switching pre-regulators.
Industrial Sensor Interfaces
Power analog sensor front-ends with a stable, adjustable rail. The low quiescent current and high PSRR help maintain measurement accuracy in noisy industrial environments.
LED Driver Reference Supply
Use the adjustable output to set a precise reference voltage for constant-current LED drivers, ensuring consistent brightness across multiple strings.
Prototyping and Bench Supplies
On a breadboard or custom PCB, this DPAK-packaged LDO is easy to solder and configure with two resistors, making it ideal for adjustable lab power supplies up to 1A.
