DESCRIPTIO

The LTC

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 avail-

able in a small 10-lead MSOP or low profile (0.75mm)

10-lead 3mm × 3mm DFN package.
