DESCRIPTION
Low Quiescent Current IQ:
The RS3007 series is a Low Dropout Linear
Regulator designed by CMOS technology. Which can
provide 300mA output current. The device allows
input voltage as high as 45V.It is very suitable for
multi-cell battery systems, bus voltage power supply
systems, Vehicle battery power supply system and
other high DC voltage systems. Wide input voltage
can make it well withstand the impact of surge voltage
and ensure the stability of output voltage.

NOTES:

2. Model A provides ± 1% precision output voltage.
3. The maximum output current of the actual chip is subject to PCB heat dissipation design, input voltage, output voltage difference and
ambient temperature.
4. Under the condition of VIN = Vout + 2V and a fixed load, the output voltage decreases by 2%. At this time, the input voltage minus the
output voltage is the dropout voltage.
5. Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range.

Function introduction
RS3007 series low dropout linear regulator (LDO) consumes only 3.0uA of current and has excellent linear
adjustment and load characteristics to meet the requirements of lower output noise and higher PSRR, making
it more suitable for applications requiring ultra-low standby power consumption of the whole machine.
Functional Block Diagram
Precautions for heat dissipation design
When the junction temperature of PN junction is too high and reaches the set temperature value, it will trigger
the thermal protection circuit to send a signal to the control logic to turn off the chip output. When the PN
junction temperature is lower than the set protection temperature, the chip will restart automatically. The
maximum output power actually provided by the chip depends on the heat dissipation design of the system,
including ambient temperature, wiring thickness and layout, and cooling design, such as adding heat sink and
air cooling. Increasing the PCB area of GND pin can also obtain better heat dissipation performance.
Other application considerations
1 ) The phase compensation circuit and ESR of the output capacitor are used inside the circuit to
compensate, so a capacitor larger than 1.0uF must be connected to the ground.
2 ) It is recommended to use 1uF polar capacitors for input and output, and to keep the capacitors as close
to the VIN and VOUT pins of LDO as possible.
3 ) Pay attention to the service conditions of input and output voltage and load current to make the junction
temperature lower than the overheat protection temperature(TSHDN).
Approximate estimation method of the junction temperature(TJ ):
TJ =(VIN-VOUT) × IOUT×RθJA+TA
IOUT is the Load current
RθJA is the Junction-to-ambient thermal resistance
TA is the ambient temperature.
Only when the TJ < TSHDN , the chip will not trigger the over-temperature protection function.
4) When the input voltage 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. If VIN lower than 2.5V, the VOUT is:
VOUT = VIN - VDropout
VDropout is converted according to the actual load current and basically maintains a linear relationship.
