*RP105Q (SC-88A) is the discontinued product as of April, 2018.
OUTLINE
The RP105x is a 400 mA output type CMOS-based voltage regulator with capability of low input voltage (Min.
0.9 V) and low output voltage (Min. 0.6 V). This device is remarkably improved the performance at low input
voltage compared with conventional low voltage LDOs, and two power supply voltage type. (Another power
source, VBIAS pin voltage must be Min. 2.4 V). The device consists of a voltage reference unit, an error amplifier,
resistor-net for voltage setting, a current limit circuit to avoid the destruction, a UVLO circuit with monitoring
input voltage, and so on.
The RP105x has the ultra-low on resistance output driver, the on resistance is Typ. 0.4 (VOUT = 0.8 V, IOUT =
300 mA). The built-in driver is Nch MOSFET, thus the load transient response is excellent, (under the condition
of the current between 1 mA and 400 mA, tr = 0.5 s, the undershoot level is approximately 50 mV).
The output voltage of this device is fixed with high accuracy. Since the packages for the device are
DFN(PLP)1212-6, DFN1212-5, SOT-23-5 and SC-88A therefore high density mounting of the IC on boards is
possible.

recommended operating conditions. The semiconductor devices cannot operate normally over the recommended
operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended operating
conditions.

TECHNICAL NOTES
UVLO (Undervoltage Lockout)
In RP105xxxxB/D, UVLO detects and turns off the output when the input voltage VIN drops lower than or equal
to VSET + 50 mV (Typ.) while CE = “H”. Since RP105xxxxE/F does not have UVLO, it continues to output even
if VIN drops to VSET + 50 mV (Typ.) or lower.
When VIN drops below the set output voltage VSET, UVLO does not turn off the output in RP105xxxxE/F while
CE = “H”, therefore the current flows from VBIAS pin to VIN pin via the inside IC. This will not be generated in
RP105xxxxB/D since UVLO turns off the output when VIN is lower than or equal to VSET + 50 mV (Typ).
Phase Compensation
In this device, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, use a capacitor for COUT with the capacity of equal or more than 2.2 F.
If tantalum capacitors are connected as COUT, and if the equivalent series resistance (ESR) value is large, the
operation might be unstable. Because of this, test the device with as same external components as ones to
be used on the PCB.
PCB Layout
Make VBIAS, VIN, and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may
result. Connect a capacitor with a capacitance value as much as 1.0 F or more between VBIAS pin and GND,
between VIN pin and GND, and as close as possible to the pins.
Set external components, especially the output capacitor, as close as possible to the device, and make wiring
as short as possible. VIN source is supposed to be the output of the DC/DC converter. The value should be
equal or lower than VBIAS voltage.

ESR vs. Output Current
Ceramic type output capacitor is recommended for this series; however, the other output capacitors with low
ESR also can be used. The relations between IOUT (Output Current) and ESR of an output capacitor are shown
below. The conditions when the white noise level is under 40 V (Avg.) are marked as the hatched area in the
graph.
Measurement conditions
Frequency Band : 10 Hz to 2 MHz
Temperature : 40C to 85C
