RICOH RP200x Technical data

RP200x Series

Manual/Automatic Mode Shift Low Voltage 300mA LDO

The RP200x Series are CMOS-based manual/automatic mode s hift LDO regulators featuring 300mA output. In auto switching mode ,
the operation can switch automaticall y to fast response mode or low power mode of the E CO function acco rding to output current.
(Automatic switching to fast response mode under I
power mode, supply current is as low as 1.5μA. In fast response mode, ripple rejection is 70dB and noise is low. By inputting control
signal into the AE pin, the mode of the regulator can be fixed w ith fast response mo de. In additio n to SOT-23-5 packages, a 0.69mm
square WLCSP-4-P5 package and a 1.2mm square DFN(PLP)1212-6 are also available.

WHAT IS ECO Function

An increasing number of devices such as mobile phones do not have only talk mode (active mode) and off mode status, but also standby mode
(sleep mode) etc.
However during the active mode and sleep mode the regulator must satisfy very different requirement. The regulators are required to have fast
response and high ripple rejection in the active mode, but consume low supply current in the sleep mode. To satisfy these conflicting requirements,
Ricoh’s regulators include an ECO function that allows switching between fast mode and low power mode.
There are some types of switching between fast mode and low power mode. As RP200x Series are automatic mode shift types, they can switch the
modes automatically depending on system load.
By inputting control signal into the AE pin, the mode of the regulator can be fixed with fast response mode.
