RT9058
36V, 2μA I_Q, 100mA Low Dropout Voltage Linear Regulator
General Description
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.
