Product Description

Overview

This 3.3 V boost (step-up) voltage regulator generates 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 3.3 V electronics projects from 1 to 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell. Additionally, unlike most boost regulators, this unit offers a true shutdown option that turns off power to the load (with typical boost regulators, the input voltage will pass directly through to the output when they are disabled).

When boosting, this module acts as a switching regulator (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and has a typical efficiency between 70% to 90%. The available output current is a function of the input voltage, output voltage, and efficiency (seeTypical Efficiency and Output Currentsection below), but the input current can typically be as high as 1.2 A. This regulator is also available with afixed 5 Voradjustableoutput, and very similar regulators are available in a much smaller size with afixed 3.3 Vorfixed 5 Voutput.

The regulator’s thermal shutdown engages at around 140°C and helps prevent damage from overheating, but it does not have reverse-voltage protection.

Features

Input voltage: 0.5 V to 5.5 V
Fixed 3.3 V output with 4% accuracy
True shutdown option that turns off power to the load
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 (<100 µA typical quiescent current withSHDN = LOW)
Integrated over-temperature shutoff
Small size: 0.45? × 0.6?; × 0.1? (12 × 15 × 3 mm)

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
Output voltage: 3.3 V
Reverse voltage protection?: N
Maximum quiescent current: 1 mA³

Identifying markings

PCB dev codes: reg12a
Other PCB markings: 0J7440

Notes:

Without included optional headers.
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.
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.
