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 required to bias it allowing ground pin current to remain below 100 µA regardless of load current, input voltage, or operating temperature. Dropout Voltage: 450 mV (typ) @ 1A (typ. 5V out). Ground Pin Current: 55 µA (typ) at full load. Precision Output Voltage: 2.5% (25°C) accuracy.
