■ 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.
