Pololu Adjustable Step-Up Voltage Regulator U1V11A
Pololu Adjustable Step-Up Voltage Regulator U1V11A
COD: 304087
COD.MEPA: 304087CS
COD.MEPA: 304087CS
Descrizione
This compact (0.45?×0.6?) U1V11A switching step-up (or boost) voltage regulator efficiently boosts input voltages as low as 0.5 V to an adjustable output voltage between 2 V and 5.25 V. Unlike most boost regulators, the U1V11A offers a true shutdown option that turns off power to the load, and it 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.
Dimensions
Size: 0.45? × 0.6? × 0.1?1
Weight: 0.7 g1
General specifications
Minimum operating voltage: 0.5 V
Maximum operating voltage: 5.5 V
Maximum input current: 1.2 A2
Minimum output voltage: 2 V
Maximum output voltage: 5.25 V
Reverse voltage protection?: N
Maximum quiescent current: 4 mA3
Notes:
1 Without included optional headers.
2 Regulator may overheat at lower input currents when VIN is much lower than VOUT. Available output current is a function of VIN, VOUT, and the regulator efficiency.
3 The highest quiescent currents occur at very low input voltages; for most of the input voltage range, the quiescent current is well below 1 mA.
