WSON (NGG)-6-9 mm² 3 x 3
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 output capacitors.
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.WELL LINK CHIPS GROUP CO.,LIMITED FLAT/RM 1802 BEVERLY HOUSE 93-107 LOCKHART ROAD WANCHAI HK
