1.8V to 1.5V, 100mA VLDO Regulator

The LT

regulator that operates from input supplies down to 0.9V.

This device supplies 100mA of output current with a

typical dropout voltage of 150mV. The LT3020 is ideal for

low input voltage to low output voltage applications,

providing comparable electrical efficiency to that of a

switching regulator.

The LT3020 regulator optimizes stability and transient

response with low ESR, ceramic output capacitors as

small as 2.2

µF. Other LT3020 features include 0% typical

line regulation and 0.2% typical load regulation. In shut-

down, quiescent current drops to 3

µA.

Internal protection circuitry includes reverse-battery pro-

tection, current limiting, thermal limiting with hysteresis,

and reverse-current protection. The LT3020 is available as

an adjustable output device with an output range down to

the 200mV reference. Three fixed output voltages, 1.2V,

1.5V and 1.8V, are also available.

The LT3020 regulator is available in the low profile

(0.75mm) 8-lead (3mm

× 3mm) DFN package with Ex-

posed Pad and the 8-lead MSOP package.
