The RT9058 is a low-dropout (LDO) linear voltage regulator featuring high input voltage, low dropout voltage, ultra-low operating current, and compact packaging. With a quiescent current as low as 2μA, the RT9058 is particularly suitable for battery-powered devices.
The RT9058's stability is easily maintained with a variety of output capacitors, including tiny ceramic capacitors, across its wide input voltage range of 3.5V to 36V and load current range of 0mA to 100mA. The RT9058 offers commonly output voltages of 2.5V, 3V, 3.3V, 5V, 6V, 9V, and 12V.
The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 85°C.
