Output Voltage Accuracy:
The RS3002 series is a set of low power high voltage
regulators implemented in CMOS technology. It can
operate from 2.5V to 36V. Which can provide 150mA
output current. The device allows input voltage as high
as 36V.
The RS3002 series is available in several fixed output
voltages. CMOS technology ensures low dropout
voltage and ultralow quiescent current.
The RS3002 is available in Green SOT23-3, SOT23
and SOT89-3L packages. It operates over an ambient
temperature range of -40°C to +85°C.

DETAILED DESCRIPTION
Overview
The RS3002 low-dropout regulators (LDO) consumes only 2.5 µA of quiescent current at light load and delivers
excellent line and load transient performance. These characteristics, combined with low noise and good PSRR
with low dropout voltage, make this device ideal for portable consumer applications.
Functional Block Diagram
Thermal Considerations
When the junction temperature is too high, the thermal protection circuitry sends a signal to the control logic
that will shut down the IC. The IC will restart when the temperature has sufficiently cooled down. The maximum
power dissipation is dependent on the thermal resistance of the case and the circuit board, the temperature
difference between the die junction and the ambient air, and the rate of air flow. The GND pin must be connected
to the ground plane for proper dissipation.
Operation with VIN Lower Than 2.5V
The device normally operates with input voltages above 2.5V. At input voltages below the 2.5V, the device does
not operate.
Operation with VIN Larger Than 2.5V
When VIN is greater than 2.5V, if VIN is also higher than the output set value plus the device dropout voltage,
VOUT is equal to the set value. Otherwise, VOUT is equal to VIN minus the dropout voltage.
