AMS1117 Description

Short technical summary and product information.

The AMS1117 series of voltage regulators from Advanced Monolithic Systems, Inc. are designed for high-efficiency linear regulation. This specific model offers a fixed 5V output voltage and can deliver up to 1A of output current. It features a low dropout voltage, guaranteed to be a maximum of 1.3V at maximum output current, making it suitable for applications where input voltage is close to the output voltage.

 

The device operates with a low input-to-output differential and is available in surface-mount packages like SOT-223, TO-252, and SO-8. Its line regulation is a maximum of 0.2%, and load regulation is a maximum of 0.4%, ensuring stable power delivery. The operating junction temperature range is -40°C to 125°C.

 

Applications for the AMS1117 include battery chargers, active SCSI terminators, and power management for portable devices like notebooks. Its on-chip trimming adjusts the reference voltage to within 1% and also trims the current limit for protection under overload conditions.
