RP152x Series
150 mA Low Voltage Dual-Channel LDO Regulator with Sequence Control
NO.EA-200-160707
OUTLINE
The RP152x is a 150 mA dual-channel LDO regulator that provides high ripple rejection, low dropout voltage,
high output voltage accuracy, and low supply current. Internally, the RP152x consists of a voltage reference
unit, an error amplifier, resistors for setting output voltage, a short current limit circuit, and a chip enable circuit.
Moreover, the RP152xxxxC consists of a start-up sequence circuit.
The RP152x is available in fixed output voltage options. Besides the low supply current by CMOS, the RP152x
offers a low dropout voltage by built-in low ON resistance Tr. as well as an extended battery life by a chip
enable function. Compared with the existing CMOS-based regulators, the RP152x is further improved in ripple
rejection, line transient response, and load transient response. All these features allow the RP152x to become
ideal power sources for hand-held communication equipment.
The RP152x is offered in a 6-pin SOT-23-6 package and a 6-pin DFN1212-6 package. Both packages are
equipped with two LDOs which can achieve high-density mounting.

Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge accumulated in the
external capacitor when the chip enable signal is switched from the active mode to the standby mode.

RECOMMENDED OPERATING CONDITIONS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
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.

THEORY OF OPERATION
Start-up Sequence Circuit
The RP152xxxxC is equipped with a start-up sequence circuit. VR2 stands-up in 100 µs delay after VR1 stands
up simultaneously with CE. Moreover, to disabling is depending upon the setting output voltage and the
external capacitors. VR1 reduces the output voltage by the Nch driver of about 50 Ω, and VR2 reduces the
output voltage by the Nch driver of about 10 Ω.

Technical Notes on the Components Selection
• In this device, phase compensation is provided to secure stable operation even when the load current
varied. For this purpose, connect 0.22 μF or more output capacitors (COUT1, COUT2) between the VOUT
and GND pin with shortest-distance wiring. In case of using a tantalum type capacitor and the ESR
(Equivalent Series Resistance) value of the capacitor is large, the output might be unstable. Evaluate the
circuit including consideration of frequency characteristics.
• Ensure the VDD and GND lines are sufficiently robust. If their impedance is too high, noise pickup or
unstable operation may result. Connect a 0.22 μF input capacitor (CIN) between the VDD and GND pins
with shortest-distance wiring. Refer to Typical Application Circuit.

Equivalent Series Resistance (ESR) vs. Output Current
It is recommended that a ceramic type capacitor be used for the RP152x. However, other types of capacitors
having lower ESR can also be used. The relation between the output current (IOUT) and the ESR of output
capacitor is shown below.
