ST5R00 - ST Microelectronics

ST5R00 (ST5R00 Series) MICROPOWER VFM STEP-UP DC/DC CONVERTER

The ST5R00 is an high efficiency VFM Step-up DC/DC converter for small, low input voltage or battery powered systems with ultra low quiescent supply current. The ST5Rxx accept a positive input voltage from start-up voltage to VOUT and convert it to a higher output voltage in the 2.5 to 5V range. The ST5R00 combine ultra low quiescent supply current and high .

Features

an inductor a diode and an output capacitor. The ST5R00 is suitable to be used in a battery powered equipment where low noise, low ripple and ultra low supply current are required. The ST5R00 is available in very small packages: SOT23-5L, SOT-89. Typical applications are pagers, cameras & video camera, cellular telephones, wireless telephones, palmtop computer, battery backup supplies, battery powered equipment.
