Description

Voltage Boost Regulator (0.5 - 5.5V In, 5V 1.2A Out)

This tiny U1V10F5 switching step-up (or boost) voltage regulator efficientlygenerates 5 V from input voltages as low as 0.5 V. Unlike most boostregulators, the U1V10F5 automatically switches to a linear down-regulationmode when the input voltage exceeds the output. The pins have a 0.1″ spacing,making this board compatible with standard solderless breadboards andperfboards. When boosting, this module acts as a switching regulator (alsocalled switched-mode power supplies (SMPS) or DC-to-DC converters) and has atypical efficiency between 70% to 90%. The available output current is afunction of the input voltage, output voltage, and efficiency (see TypicalEfficiency and Output Current section below), but the input current cantypically be as high as 1.2 A.

Features

  • Input voltage: 0.5 V to 5.5 V
  • Fixed 5 V output with 4% accuracy
  • 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: 9 × 11.5 × 2.5 mm

    Specifications:

  • Minimum operating voltage: 0.5 V

  • Maximum operating voltage: 5.5 V
  • Maximum input current 1.2A
  • Output voltage: 5 V
  • Reverse voltage protection?: N
  • Maximum quiescent current: 1mA
  • Pin Spacing 2.54mm

    Using the Regulator

Connections - The boost regulator has three connections: input voltage (VIN),ground (GND), and output voltage (VOUT).

The input voltage, VIN, must be at least 0.5 V for the regulator to turn on.However, once the regulator is on, the input voltage can drop as low as 0.3 Vand the 5 V output voltage will be maintained on VOUT. Unlike standard boostregulators, this regulator has an additional linear down-regulation mode thatallows it to convert input voltages as high as 5.5 V down to 5 V for small tomoderate sized loads. When the input voltage exceeds 5 V, the regulatorautomatically switches to this down-regulation mode. The input voltage shouldnot exceed 5.5 V. Please be wary of destructive LC spikes that might cause theinput voltage to surpass 5.5 V (see below for more information).

The three connections are labeled on the back side of the PCB, and they arearranged with a 0.1″ (2.54mm) spacing along the edge of the board forcompatibility with solderless breadboards, connectors, and other prototypingarrangements that use a 0.1″ grid. You can solder wires directly to the boardor solder in either the 3×1 straight male header strip or the 3×1 right-anglemale header strip that is included.
