Description

The LP2985-XX is a 150 mA, fixed output voltage regulator designed o provide very low dropout and low noise in battery powered and ortable applications. The output voltage is preset to 1.8, 2.8, 3.0, .3, 3.6, or 5.0 V.

Designed with an optimized PNP process, the LP2985-XX achieves nequalled performance in all specifications critical to attery-powered designs such as low supply-current, low dropout oltage, low power consumption, small size, fast dynamic response o line and load, precision output, etc. This regulator consists of an nternal voltage reference, an error amplifier, a driver with current imiter and a thermal shut-down mechanism.

THe LP2985-XX is housed in a SOT23-5 5-lead package.
