The ST5R00 series is a low power step-up DC/DC converter from STMicroelectronics. It has a wide input voltage range and adjustable output voltage, and is suitable for use in battery powered equipment.
The ST5R00 Series is an efficient VFM (Voltage Feedback Mode) Step-Up DC/DC converter designed for small, low-input voltage, or battery-powered systems. It features very low quiescent supply current and high efficiency, making it suitable for applications like pagers, cameras, cellular telephones, and wireless devices. The series offers a wide range of regulated output voltages including 2.5V, 2.8V, 3.0V, 3.3V, and 5.0V.
| Output Voltage Range | 2.5V to 5V |
|---|---|
| Maximum Output Current | 100mA |
| Supply Current (No Load) | 16 pA |
| Maximum Oscillator Frequency | 150 kHz |
| Efficiency (Vout=5V) | 87% |
| Operating Junction Temperature | -25 to +85 °C |
The ST5Rxx models accept input and provide regulated outputs of 2.5V, 2.8V, 3.0V, 3.3V, or 5.0V.
Only three external components are needed: an inductor, a diode, and an output capacitor.
The absolute maximum rating for both Input Voltage (Vin) and Output Voltage (Vout) is 5.5 V.
