LD39080PT18-R

LD39080 Ultra low drop BiCMOS voltage regulator Datasheet - production data Applications Microprocessor power supply DSP power supply Post regulators for switching suppliers High efficiency linear regulator Description PPAK The LD39080 is a fast, ultra low drop linear regulator which operates from 2.5 V to 6 V input supply. A wide range of output options is available. The low drop voltage, low noise, and ultra low Features quiescent current make it suitable for low voltage microprocessors and memory applications. The 0.8 A guaranteed output current device is developed on the BiCMOS process Ultra low-dropout voltage (150 mV typ. 0.8 A which allows the low quiescent current operation load, 20 mV typ. 150 mA load) regardless of the output load current. Very low quiescent current (1 mA typ. 0.8 A load, 1 A max. 25 C in off mode) Table 1.
