U1V10x Step-Up Voltage Regulators
 |
These small adjustable boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 0.5 V, and it also automatically switches to a linear down-regulation mode when the input voltage exceeds the output. This makes it great for powering electronics projects from 1 to 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell.
Features
- Input voltage: 0.5 V to 5.5 V
- Automatic linear down-regulation when the input voltage is greater than the output voltage
- 1.2 A switch allows for input currents up to 1.2 A
- Good efficiency at light load: <1 mA typical no-load quiescent current, though it can exceed 1 mA for very low input voltages
- Integrated over-temperature shutoff
- Small size: 0.35″ × 0.45″ × 0.1″ (9 × 11.5 × 2.5 mm)

This tiny (0.35″×0.45″) U1V10F3 switching step-up (or boost) voltage regulator efficiently generates 3.3 V from input voltages as low as 0.5 V. Unlike most boost regulators, the U1V10F3 automatically switches to a linear down-regulation mode when the input voltage exceeds the output. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.
