illustrate

LP38513 fast-response ultra-low dropout linear regulator operates from a 2.25 V to 5.50 V input supply. This ultra-low dropout linear regulator has a very fast response time under step changes or load conditions, which makes it suitable for use in low-voltage microprocessor applications. CMOS process development of PMOS bypass transistors LP38513 operation with low quiescent current is independent of the output load current.

Ground Pin Current: Generally a load current of 12 mA at 3A.

Ban Mode: At a quiescent current of 60μA, the enable pin is pulled down.

^Error flags: ^Error flags become low, if V OUT drops usually below more than 15% of nominal value.

Precision Output Voltage: The output accuracy of V is guaranteed ± 2.6% T J from 0°C to 125°C.
