OUTLINE
The R5310L Series are Multi LDO regulators for power management of cellular phones. All of regulators are low noise and
extremely low quiescent current by CMOS process. Each of these ICs consists of eight LDOs, voltage detectors, battery
monitor, three LED drivers, and a ringer driver. Each of them can be controlled by CPU via 3-wire serial interface. These ICs
make it possible to integrate almost power management and analog drivers in cellular-phone systems. The output voltage of
two regulators are externally programmable, and other regulators are able to set different output voltage independently by laser
trim as well as detector thresholds.
A tiny 32-pin LQFP, 0.5mm lead pitch, is available.
