Dual, 300 mA Adjustable Output, Low Noise, High PSRR Voltage Regulator

Manufactured by:

Product Details

The 300 mA, adjustable dual output ADP223/ADP225 and fixed dual output ADP222/ADP224 combine high PSRR, low noise, low quiescent current, and low dropout voltage in a voltage regulator that is ideally suited for wireless applications with demanding performance and board space requirements.

The low quiescent current, low dropout voltage, and wide input voltage range of the ADP222/ADP223/ADP224/ADP225 extend the battery life of portable devices.

The ADP222/ADP223/ADP224/ADP225 maintain power supply rejection greater than 60 dB for frequencies as high as 100 kHz while operating with a low headroom voltage. The ADP222/ADP223/ADP224/ADP225 offer much lower noise performance than competing LDOs without the need for a noise bypass capacitor. Overcurrent and thermal protection circuitry prevent damage in adverse conditions.

The ADP224 and ADP225 are identical to the ADP222 and ADP223, respectively, but with the addition of a quick output discharge (QOD) feature.

The ADP222/ADP223/ADP224/ADP225 are available in a small 8-lead, 2 mm x 2 mm LFCSP package and are stable with tiny 1 μF, ±30% ceramic output capacitors, resulting in the smallest possible board area for a wide variety of portable power needs.

EVAL-ADP223 Circuit Diagram

Product Details

The ADP223 evaluation board is used to demonstrate the functionality of the ADP223 dual adjustable linear regulator.

Simple device measurements, such as line and load regulation, dropout voltage, and ground current consumption, can be demonstrated with only a single voltage supply, voltmeters, a current meter, and load resistors.
