The LT3060 series are micropower, low dropout voltage (LDO) linear regulators that operate over a 1.6V to 45V input supply range. The devices supply 100mA of output current with a typical dropout voltage of 300mV. A single external capacitor provides programmable low noise reference performance and output soft-start functionality. The LT3060’s quiescent current is merely 40μA and provides fast transient response with a minimum 2.2μF output capacitor. In shutdown, quiescent current is less than 1μA and the reference soft-start capacitor is reset.
The LT3060 regulators optimize stability and transient response with low ESR, ceramic output capacitors. The regulators do not require the addition of ESR as is common with other regulators.
Internal protection circuitry includes reverse-battery protection, reverse-output protection, reverse-current protection, current limit with foldback and thermal shutdown. The LT3060 series are available in fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V and 15V, and as an adjustable voltage regulator with an output voltage range from the 600mV reference to 44.5V. The LT3060 regulators are offered in the thermally enhanced 8-lead TSOT-23 and 8-lead (2mm × 2mm × 0.75mm) DFN packages.

Evaluation Kits (1)
Demonstration circuit 1209A is a Micropower, low dropout linear regulator featuring LT3060, which comes in an 8-lead TSOT23 or 2mm × 2mm DFN package. The DC1209A has an input voltage range from 2.1V to 45V, and is capable of delivering up to 100mA output current. The jumper-selectable output voltage can be set to 1.2V, 1.5V, 1.8V, 2.0V, 2.5V, 3.3V, 5V or a user-defined value. An external capacitor at REF/BYP pin provides low noise reference and programmable output soft-start functionality. The LT3060’s quiescent current is merely 40µA and provides fast transient response with a minimum 2.2µF output capacitor.
