RP200x SERIES
3-MODE 300mA LDO REGULATOR
NO.EA-182-100208

OUTLINE
The RP200x Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy, low
dropout voltage and low supply current. These ICs perform with the chip enable function and realize a standby
mode with ultra low supply current. To prevent the destruction by over current, the current limit circuit is included.
The RP200x Series have 3-mode. One is standby mode with CE pin. Other two modes are realized with ECO
Function. Fast Response Mode (Fast Mode) and Fast and Low Power auto-change Mode (Auto ECO Mode) are
alternative with Auto Eco pin (AE pin). Supply current of IC itself at light load is automatically reduced at Auto
ECO Mode compared with Fast Mode. The output voltage is maintained between Fast Mode and Auto ECO
Mode.
Without AE pin type is also available. It is an LDO regulator with Auto ECO mode. (RP200Z in WLCSP.)
Since the packages for these ICs are SOT-23-5, SC-88A, thin DFN(PLP)1212-6, and WLCSP-4-P5, high
density mounting of the ICs on boards is possible. RP200Q (SC-88A), RP200K (DFN(PLP)1212-6) and RP200N
(SOT-23-5) has AE pin, then if the AE pin is "H", Fast Mode is available. If the AE pin is set at "L" level, Auto ECO
Mode operation is available.
