R5326 Datasheet, PDF (1/27 Pages) RICOH electronics devices division – Supply Current (Low Power Mode) Typ. 5.5μA×2 (VR1&VR2) (IOUT=0mA)

R5326N (SOT-23-6) and R5326Z (WLCSP-6-P1) are the discontinued product. As of June in 2016.
R5326x SERIES
Automatic Mode Shift Dual 150mA LDO
NO.EA-138-140530
OUTLINE
The R5326x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, Typ. 5.5μA low
supply current, and remarkably improved transient response compared with the conventional low supply current
voltage regulators. The supply current of IC itself is automatically shifts between fast mode and low power mode
depending on the load current. (The current threshold is fixed internally.) Each of these voltage regulator ICs
consists of a voltage reference unit, an error amplifier, resistors for setting the output voltage, a current limit
circuit for preventing from the destruction by an over current, and so on.
The chip enable function realizes the standby mode with ultra low supply current.
Since the packages for these ICs are SOT-23-6 and DFN(PLP)1820-6, and chip size package, WLCSP-6-P1,
dual LDO regulators are included in each package, high density mounting of the ICs on boards is possible.
