00 — Overview

What the RT9013-1 family does

The RT9013-x family comprises 500mA low dropout regulators with fixed outputs ranging from 1.2V to 3.3V. These devices operate across a 2.2V to 5.5V input range while maintaining a 250mV dropout at full load. They feature ultra-low noise suitable for RF applications, a quiescent current as low as 25μA, and high power supply rejection. The regulators support fast transient response without bypass capacitors and include thermal shutdown protection. Engineers typically use them in portable wireless devices, cellular handsets, and handheld instruments where space and battery life are critical constraints.
