The LP38690/2 low-dropout CMOS linear regulator offers tight output tolerances (2.5% typical) with very low dropout (450mV @ 1A load current).
，
V
OUT = 5V), and excellent AC performance with ultra-low ESR ceramic output capacitors.
The SOT-223 and T0-252 packages have low thermal resistance LLP that enables the entire operating current, even in environments with high ambient temperatures.
The use of a PMOS power transistor means that no DC base drive current is required for biasing, which keeps the ground pin current below 100μA regardless of load current, input voltage, and operating temperature.
Differential pressure:
450 mV (typical) @ 1A (typical 5V output).
Ground pin current:
55μA (typical) at full load.
Precision output voltage:
2.5% (25°C) accuracy.
