LP38691/LP38693 500mA Low Dropout CMOS Linear
Regulators Stable with Ceramic Output Capacitors
General Description
The LP38691/3 low dropout CMOS linear
regulators provide tight output tolerance (2.
0% typical), extremely low dropout voltage (250 mV @ 500mA 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 ...
