Description

The AP7369Q series is a wide input-voltage range (45V), low quiescent current (2.1µA), low-dropout linear regulator (LDO) able to provide 150mA load current.

The device provides a very fast response against line voltage transient and load current transient, and ensures no overshoot voltage occurs during startup and short-circuit recovery. It also features integrated short-circuit and thermal-shutdown protection.

The AP7369Q has 2.5V, 3.3V, and 5.0V fixed output voltage versions. It is available in the SOT25 package, and will be available in the SOT223 package.

Feature(s)

  • Wide Input-Voltage Range: 3V to 45V
  • Maximum Output Current: 150mA
  • Low Dropout Voltage:

VDROP = 35mV @ IOUT = 10mA (typ)

VDROP = 350mV @ IOUT = 100mA (typ)

  • Low Quiescent Current: 2.1μA (typ)
  • Fixed Output Voltages: 2.5V, 3.3V and 5.0V
  • High Output Voltage Accuracy: ±2%
  • High PSRR: 85dB@1kHz
  • Excellent Line/Load Regulation
  • Thermal Shutdown Function
  • Short-Current Protection Function
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
  • Halogen and Antimony Free. “Green” Device (Note 3)
  • The AP7369Q is suitable for automotive applications requiring specific change control; this part is AEC-Q100 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. https://www.diodes.com/quality/product-definitions/
