1μA IQ, 250mA Low-Dropout Linear Regulator


Update Alert Share

The RT9063 is a low-dropout (LDO) linear regulator that features high input voltage, low dropout voltage, ultra-low operating current, and miniaturized packaging. With quiescent current as low as 1μA, the RT9063 is ideal for battery-powered equipment.

The RT9063's stability requirements are easily met with all types of output capacitors, including tiny ceramic capacitors, over its wide input range and its load current range (0mA to 250mA). The RT9063 offers standard output voltages of 1.2V, 1.5V, 1.8V, 2.5V and 3.3V.
