AP7353D-33CV4-7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7353D-33CV4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a nominal output voltage of 3.3 V with an accuracy of ±1%. It supports a maximum output current of 250 mA and operates within an input voltage range of 2.0 V to 5.5 V. The device features a typical quiescent current of 18 µA and includes an enable pin for power management. Packaged in the X1-WLB0707-4 (Type A1) format, it incorporates built-in output discharge functionality.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated N-channel auto-discharge resistor that activates when the enable pin is low to rapidly dissipate stored charge from the output capacitor.
• High ripple rejection performance ensuring stable operation in noise-sensitive environments.
• Low output noise characteristics suitable for precision analog and RF circuitry.
• Built-in thermal shutdown and current limit protection mechanisms.
