LP38690/LP38692 1A Low Dropout CMOS Linear
Regulators Stable with Ceramic Output Capacitors
General Description
The LP38690/2 low dropout CMOS linear
regulators provide tight output tolerance (2.
5% typical), extremely low dropout voltage (450mV @ 1A load current, VOUT = 5V), and excellent AC performance utilizing ultra low ESR ceramic output capacitors.
The low thermal resistance of the LLP, SOT-223 and T0-252 packages allow the full operating current to be used even in high ambient temperature environments.
The use of a PMOS power
transistor means that no DC base drive current is requi...
