Low Dropout Regulator from Diodes Offers High PSRR in Small Footprint

05.06. 2020 | News

Diodes announced the AP7353 low dropout regulator, which offers a high power supply rejection ratio (PSRR) in a small package, meeting the need for voltage regulation in noise-sensitive, battery-operated devices such as wearables, portables, and connected sensors.

The AP7353 is available in X1-WLB0707-4 (Type A1) and X2-DFN1010-4 (Type B) packages, each measuring less than 1mm on each side. These dimensions result in a small footprint that supports densely populated printed circuit board layouts. Despite its size, the AP7353 delivers the voltage and current levels demanded by the latest electronic devices now being deployed into the IoT, up to 4.5V at 250mA.

A PSRR of 90dB at 1kHz and low quiescent current of 18μA make the AP7353 particularly suitable for battery-powered devices that include noise-sensitive analog circuits or RF interfaces. The AP7353’s high PSRR and its 10µV wideband noise voltage help support a high signal-to-noise ratio (more info).
