The LTC3026 is a very low dropout (VLDO) linear regulator that can operate at input voltages down to 1.14V. The device is capable of supplying 1.5A of output current with a typical dropout voltage of only 100mV. To allow operation at low input voltages the LTC3026 includes a boost converter that provides the necessary headroom for the internal LDO circuitry.

Output current comes directly from the input supply to maximize efficiency. The boost converter requires only a small chip inductor and ceramic capacitor for operation. Additionally, the boosted output voltage of one LTC3026 can supply the boost voltage for other LTC3026s, thus requiring a single inductor for multiple LDOs. A user supplied boost voltage can be used eliminating the need for an inductor altogether.

The LTC3026 regulator is stable with 10μF or greater ceramic output capacitors. The device has a low 0.4V reference voltage which is used to program the output voltage via two external resistors. The device also has internal current limit, overtemperature shutdown, and reverse output current protection. The LTC3026 is available in a small 10-lead MSOP or low profile (0.75mm) 10-lead 3mm × 3mm DFN package.

Product Detail

Demonstration circuit 833 is an ultralow dropout voltage supply using the 1.5A output current LTC3026 linear regulator in a small 3mm × 3mm 10-Pin DFN package. The DC833 has an input voltage range from 1.14V to 3.5V when the internal boost converter is enabled, and a maximum input voltage of 5.5V when an external source is supplied. The output voltage jumper-selectable and can be set to 0.8V, 1.2V, 1.5V, 1.5V, 1.8V or a user-defined value between 0.4V and 2.6V. The 0.4V reference of the LTC3026 allows the DC833 to supply power to very low voltage applications. The DC833 is also an excellent choice for post regulation of step-down switching regulators, creating a high efficiency low-noise supply. The DC833 comes assembled with small ceramic capacitors, showing the LTC3026's ability to maintain stability with ceramic output capacitors.
