Recom R-78S Switching Regulator 0.1 A
The R-78S is a DC-DC boost converter designed to run from single cell batteries. The input voltage range of 0.65V-3.15V means that alkaline, NiCd, NiMH, zinc-carbon or lithium chemistry cells can be used to generate a stable 3.3 V output to power microprocessors, WLAN/Bluetooth modules and IoT systems. The high efficiency and low standby consumption can be used to extend battery lifetimes until the "last gasp" to get the maximum available energy out of the cell. The wide operating temperature of -40°C to +100°C, short circuit protection, OTP, Class A EMC and 3-year warranty round off this high performance converter.

RECOM Switching Regulator, 11.6mm Length, 8.5mm Width - R-78S Series - R-78S3.3-0.1
To keep DC-powered equipment happy, add this switching regulator from RECOM to your setup. By adjusting an input voltage supply between 0.65 and 3.15V DC to a safe output voltage of 3.3V DC, it helps to protect circuits from damaging undervoltage or overvoltage conditions. Integrated short-circuit protection means this unit shrugs off current faults. As it also comes with over-temperature protection, it reliably handles demanding operations, even when the heat is on.
Features & Benefits
• Compact external dimensions of 11.6 (L) x 8.5 (W) x 10.4mm (D) to fit in limited spaces
• Typical output ripple and noise of 100mV p-p for reduced electrical disturbance
• Vibration resistance for stability in harsh conditions
• Mean time between failures of 78,172,000 hours for lasting use
