Diodes Incorporated<\/a><\/strong> announces 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.<\/p>\n\n\n\n

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. <\/p>\n\n\n\n

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. <\/p>\n\n\n\n

A PSRR of 90dB at 1kHz and low quiescent current of 18\u03bcA make the AP7353 particularly suitable for battery-powered devices that include noise-sensitive analog circuits or RF interfaces. <\/p>\n\n\n\n

The AP7353\u2019s high PSRR and its 10\u00b5V wideband noise voltage help support a high signal-to-noise ratio. These attributes position the AP7353 as a leading low-dropout (LDO) regulator in this application space.<\/p>\n\n\n\n

The AP7353\u2019s enable pin allows the LDO regulator to be put into standby mode when not required. <\/p>\n\n\n\n

For improved robustness, short-circuit and overtemperature protection are also included. An AP7353D version is available that discharges the output when disabled.<\/p>\n\n\n\n

Operating from a wide input voltage range of between 2.0V and 5.5V, the AP7353 has a fixed output voltage of between 1.8V and 4.5V with an accuracy of \u00b11% and line regulation of 0.001%\/mA when supplying an output current from 1mA to 250mA.<\/p>\n","protected":false},"excerpt":{"rendered":"
