LD39080 Ultra low drop BiCMOS voltage regulator Datasheet - production data Temperature range: -40 to 125 C Fast dynamic response to line and load changes Stable with ceramic capacitor Available in PPAK, DPAK and DFN8 (4x4 mm) DPAK PPAK Applications Microprocessor power supply DSP power supply Post regulators for switching suppliers DFN8 (4x4 mm) High efficiency linear regulator Features Description 0.8 A guaranteed output current The LD39080 is a fast, ultra low drop linear regulator which operates from 2.5 V to 6 V input Ultra low-dropout voltage (150 mV typ. 0.8 A supply. load, 20 mV typ. 150 mA load) Very low quiescent current (1 mA typ. 0.8 A A wide range of output options is available. The load, 1 A max. 25 C in off mode) low drop voltage, low noise, and ultra low quiescent current make it suitable for low voltage Logic-controlled electronic shutdown microprocessors and memory applications. The Current and thermal internal limit device is developed on the BiCMOS process 1.5% output voltage tolerance 25 C which allows the low quiescent current operation regardless of the output load current. Fixed and ADJ output voltages: 1.22 V, 1.8 V, 2.5 V, 3.3 V, ADJ Table 1.
