The unique feature compensation of the National FlexCap LDO allows the use of any type of output capacitor with no minimum or maximum ESR restrictions. The LP38500/2 series low-dropout linear regulators operate from a +2.7 V to +5.5 V input supply. These ultra-low dropout linear regulators respond very quickly to one-step loads, which makes them suitable for use in variations in low-voltage microprocessor applications. A CMOS process (utilizing PMOS bypass transistors) was developed with LP38500/2 with low quiescent current and small load current variations.

Ground Pin Current: Typically 2 mA load current of 1.5A.

Ban Mode: Typically 25 NA quiescent current when the enabling pin is pulled down.

Simplified Compensation: With any type, regardless of the output capacitance of the ESR.

Precision Output: "One" can be used with 1.5% V ADJ. Tolerance (25°C) and more than 3% line, load and temperature class versions.
