The LP3869x low-dropout CMOS linear regulators provide tight output tolerance (2%
typical), extremely low dropout voltage (250 mV at 500-mA load current, VOUT
= 5 V), and excellent AC performance using ultralow equivalent series resistance (ESR) ceramic
The low thermal resistance of the WSON, SOT-223, and TO-252 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 ground pin current to remain below 100 µA regardless of load current, input
voltage, or operating temperature.
For all available packages, see the orderable addendum at the
end of the data sheet.
