Diodes Incorporated (Nasdaq: DIOD) today 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.

Key Points: 
  • Diodes Incorporated (Nasdaq: DIOD) today 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.
  • The AP7353s high PSRR and its 10V wideband noise voltage help support a high signal-to-noise ratio.

The AP7345D family features an excellent PSRR of 75dB at 1kHz, across the full output voltage range.

Key Points: 
  • The AP7345D family features an excellent PSRR of 75dB at 1kHz, across the full output voltage range.
  • The input voltage range extends from 1.7V to 5.25V and each of the two channels can deliver up to 300mA, guaranteed.
  • The addition of an LDO enables more of the primary cells voltage to be used, extending the useful lifetime between battery changes.
  • In addition, choosing an LDO with high PSRR ensures a steady and regulated supply voltage to sensitive integrated circuits.
