The AMS1117-ADJ from EVVO is a versatile adjustable low dropout linear regulator capable of delivering up to 1A of current. With a reference voltage of 1.25V, the output can be set from 1.25V to higher voltages using external resistors, as demonstrated by the 10.7V configuration in the technical data. It features a low dropout voltage of 1.3V at full load and a high PSRR of 75dB at 120Hz, ensuring clean and stable power. The SOT-223-3L package offers a compact solution for custom power supply designs.
- Design Flexibility: Adjustable output from 1.25V up to input minus dropout, supporting a wide range of applications.
- High Current Capability: 1A output current handles demanding loads with ease.
- Low Noise Operation: 75dB PSRR at 120Hz provides clean power for sensitive analog circuits.
- Simple External Configuration: Only two resistors are needed to set the desired output voltage.
Variable Power Supplies
The adjustable output allows designers to set any voltage from 1.25V up to the input minus dropout, making it perfect for bench power supplies and lab equipment.
Custom Voltage Rails
For non-standard voltages like 3.3V, 2.5V, or 10.7V, the AMS1117-ADJ provides flexibility using two external resistors, eliminating the need for multiple fixed regulators.
Battery Charging Circuits
It can be used to create precise charging voltages for Li-ion or lead-acid batteries, where accurate voltage control is essential for battery health.
Audio Amplifier Biasing
The adjustable output enables precise biasing voltages for op-amps and audio preamplifiers, improving signal fidelity and reducing distortion.
FPGA and DSP Core Power
Many FPGAs require specific core voltages (e.g., 1.8V, 2.5V). The AMS1117-ADJ can be tuned to match these requirements, ensuring reliable operation.
Sensor Reference Voltages
Precision sensors often need a stable, adjustable reference voltage. This regulator provides a low-noise solution for such applications.
