ST5R25MTR Description

Short technical summary and product information.

The STMicroelectronics ST5R25MTR is a high-efficiency, micropower VFM step-up DC/DC converter. It is designed for small, low input voltage or battery-powered systems requiring ultra-low quiescent supply current. The converter accepts a positive input voltage and converts it to a higher output voltage, with this specific model providing a fixed 2.5V output.

 

Key electrical specifications include an output current capability of up to 100mA and a typical switching frequency of 150kHz. The device operates within a temperature range of -25°C to 85°C. It features a step-up topology and a fixed output type, with no synchronous rectifier.

 

The ST5R25MTR is housed in a very small SOT-23-5 package, making it suitable for space-constrained applications. Its design allows for the use of small, low-cost inductors, requiring only three external components: an inductor, a diode, and an output capacitor. This makes it ideal for applications where low noise, low ripple, and ultra-low supply current are critical for maximizing battery life.

 

Typical applications include pagers, cameras, cellular telephones, wireless telephones, palmtop computers, and battery backup supplies.
