RT9058
36V, 2μA IQ, 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.

Operation
The RT9058 is a high input voltage linear regulator
specifically designed to minimize external components.
The input voltage range is from 3.5V to 36V.
Output Transistor
The RT9058 includes a built-in low on-resistance
P-MOSFET output transistor for low dropout voltage
applications.
Error Amplifier
The Error Amplifier compares the output feedback voltage
from an internal feedback voltage divider to an internal
reference voltage and controls the P-MOSFET's gate
voltage to maintain output voltage regulation.

Current Limit Protection
The RT9058 provides a current limit function to prevent
damage during output over-load or shorted-circuit
conditions. The output current is detected by an internal
sensing transistor.
Over Temperature Protection
The over temperature protection function will turn off the
P-MOSFET when the internal junction temperature
exceeds 150°C (typ.) and the output current exceeds 4mA.
Once the junction temperature cools down by
approximately 20°C, the regulator will automatically
resume operation.
