3 Description
The LP38690 and LP38692 low-dropout CMOS linear regulators provide tight output tolerance (2.5% typical), extremely low dropout voltage (450 m V at a 1-A load current, VOUT = 5 V), and excellent AC performance utilizing ultra low ESR ceramic output capacitors.
The low thermal resistance of the WSON, SOT-223, and TO-252 packages allow the full operating current to be used even in...
