3-MODE 300mA LDO REGULATOR
RP200x SERIES
Preliminary
NO. EA-182-080911
OUTLINE
The RP200x Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy 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 or standby control pin. Other two modes are realized with FMODE pin™.
Fast Transient Mode (FT mode) and Fast mode and Low Power auto-change Mode (Auto ECO mode) are
alternative with Auto-Eco pin (AE pin). Consumption current of IC itself at light load is automatically reduced at
Auto ECO Mode compared with Fast Transient Mode. The output voltage is maintained between FT mode and
Auto ECO mode.
Without FMODE pin type is also available. It is an LDO regulator with Auto ECO mode. (RP200Z in WLCSP.)
Since the packages for these ICs are SOT23-5, SC-88A, thin DFN(PLP)1212-6, and WLCSP-4-P5 packages,
high density mounting of the ICs on boards is possible. RP200Q(SC-88A), RP200K (DFN(PLP)1212-6) and
RP200N (SOT23-5) has Auto ECO pin (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.
