LD39150 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 DFN6 (3x3 mm) PPAK DPAK Applications Microprocessor power supply DSPs power supply Post regulators for switching suppliers DFN6 (3 x 3 mm) High efficiency linear regulator Description Features The LD39150 is a fast ultra low drop linear regulator which operates from 2.5 V to 6 V input 1.5 A guaranteed output current supply. Ultra low dropout voltage (200 mV typ. 1.5 A load, 40 mV typ. 300 mA load) A wide range of output options are available. The low drop voltage, low noise, and ultra low Very low quiescent current (1 mA typ. 1.5 A quiescent current make it suitable for low voltage load, 1 A max 25 C in off mode) microprocessor and memory applications. The Logic-controlled electronic shutdown device is developed on a BiCMOS process which Current and thermal internal limit allows low quiescent current operation independently of output load current. 1.5% output voltage tolerance 25 C Fixed and ADJ output voltages: 1.8 V, 2.5 V, 3.3 V, ADJ Table 1.
