LP38691SD-3.3/NOPB Part Information
Details for LP38691SD-3.3/NOPB by Texas Instruments
Semiconductors - ICs>Power Management ICs - PMIC>Voltage Regulators
Part Description
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.
