GENERAL DESCRIPTION
The
ADP5303
is high efficiency, ultralow quiescent current
step-down regulator that draws only 240 nA quiescent current
to regulate the output at no load.
The
ADP5303
runs from an input voltage of 2.15 V to 6.50 V,
allowing the use of multiple alkaline or NiMH cells, Li-Ion cells,
or other power sources. The output voltage is selectable from 0.8 V
to 5.0 V by an external VID resistor and a factory fuse. The total
solution requires only four tiny external components.
The
ADP5303
can operate between hysteresis mode and PWM
mode via the SYNC/MODE pin. In hysteresis mode, the regulator
achieves excellent efficiency at less than 1 mW and provides up
to 50 mA of output current. In PWM mode, the regulator produces
a lower output ripple and supplies up to 500 mA of output current.
The flexible configuration capability during operation of the device
enables very efficient power management to meet both long battery
life and low system noise requirements.
The
ADP5303
integrates an ultralow power comparator with a
factory programmable voltage reference to monitor the input
battery voltage. The regulator runs at a 2 MHz switching frequency
in PWM mode and the SYNC/MODE pin can be synchronized
to an external clock from 1.5 MHz to 2.5 MHz.
Other key features in the
ADP5303
include separate enabling,
QOD, and safety features such as overcurrent protection (OCP),
thermal shutdown (TSD), and input undervoltage lockout
(UVLO).
The
ADP5303
is available in 9-ball, 1.65 mm × 1.87 mm
WLCSP package rated for the −40°C to +125°C junction
temperature range.
