The ADP5300 is a high efficiency, ultralow quiescent current step-down regulator that draws only 180 nA quiescent current to regulate the output at no load.

The ADP5300 runs from an input supply voltage range of 2.15 V to 6.50 V, allowing the use of multiple alkaline or NiMH, 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 factory fuse. The total solution requires only four tiny external components.

The ADP5300 can operate between hysteresis mode and PWM mode via the SYNC/MODE pin. The regulator in hysteresis mode achieves excellent efficiency at a power of less than 1 mW and provides up to 50 mA of output current. The regulator in PWM mode 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 the longest battery life and low system noise requirements.

The ADP5300 contains a VOUTOK flag, which monitors the output voltage and runs at a 2 MHz switching frequency in PWM mode. SYNC/MODE can be synchronized to an external clock from 1.5 MHz to 2.5 MHz.

The ADP5300 includes an STOP pin that can disable the regulator switching temporarily, in this way a quiet system environment can be achieved to benefit noise sensitive circuitry, such as data conversion, RF data transmit, and analog sensors.

Other key features in the ADP5300 include separate enabling, QOD, and safety features such as overcurrent protection (OCP), thermal shutdown (TSD), and input undervoltage lockout (UVLO).

The ADP5300 is available in 10-lead, 3 mm × 3 mm LFCSP rated for −40°C to +125°C junction temperature range.

Multifunction pin names may be referenced by their relevant function only.

Product Detail

The ADP5300 is an ultralow power, synchronous step-down dc-to-dc regulator with a load switch in a 10-lead LFCSP package. The ADP5300 runs from an input voltage range of 2.15 V to 6.50 V and requires minimal external components to provide a high efficiency solution with an integrated power switch, a synchronous rectifier, and internal compensation.


The ADP5300-EVALZ evaluation board provides an easy way to evaluate the device. This user guide describes how to quickly set up the board to collect performance data.


Complete information about the ADP5300 is available in the ADP5300 data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
