Part Description

The LP3869x-ADJ low-dropout CMOS linear regulators provide 2% precision reference voltage, extremely low dropout voltage (250 mV at 500-mA load current, VOUT = 5 V), and excellent AC performance using ultra-low equivalent series resistance (ESR) ceramic output capacitors. The low thermal resistance of the WSON and SOT223 packages allow use of the full operating current even in high ambient temperature environments. The use of a PMOS power transistor means that no DC base drive current is required to bias it, thus allowing the GND-pin current to remain below 100 µA regardless of load current, input voltage, or operating temperature.
