The RT9058 is a low dropout (LDO) linear voltage regulator that features high input voltage, low dropout voltage, ultra-low operating current, and miniaturized packaging. With quiescent current as low as 2μA, the RT9058 is ideal for battery-powered equipment.

The RT9058's stability requirements are easily met with all types of output capacitors, including tiny ceramic capacitors, over its wide input range (3.5V to 36V) and its load current range (0mA to 100mA). The RT9058 offers standard output voltages of 2.5V, 3V, 3.3V, 5V, 6V, 9V and 12V.
