General Description
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.

Operation
The RT9063 is a high input voltage linear regulator
specifically designed to minimize external components.
The minimum required output capacitance for stable
operation is 1μF effective capacitance after consideration
of the temperature and voltage coefficient of the capacitor.
Output Transistor
The RT9063 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
The RT9063 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
30mA. Once the junction temperature cools down by
approximately 20°C, the regulator will automatically
resume operation.
