AP7372-33CBA6-7 is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists Diodes Incorporated. Its product description is LDO LOW VOLTAGE STANDARD U-WLB10. Review the specifications below when checking this part for your BOM.
The AP7372-33CBA6-7 is a high-voltage low dropout regulator manufactured by Diodes Incorporated. It operates within an input voltage range of 2.7 V to 20 V and provides a fixed 3.3 V output with a maximum current of 200 mA. The device features ultra-low noise performance at 8 µV RMS and high power supply rejection ratios, reaching 90 dB at 10 kHz. It utilizes a U-WLB1012-6 package and supports operation across temperatures from -40°C to +125°C.
Verify the specific suffix CBA6 against official Diodes Incorporated documentation to confirm pinout and thermal characteristics. Ensure the selected component matches the required 3.3 V fixed output configuration. Cross-reference the U-WLB1012-6 package dimensions with PCB layout guidelines before finalizing procurement orders.
Select this component when system requirements demand low noise performance alongside high input voltage tolerance. The 200 mA output current suits moderate load applications. Consider the 8 µV RMS noise floor for sensitive analog signal chains. Verify that the 2.7 V minimum input voltage aligns with the source rail availability under all operating conditions.
This part belongs to the AP7372 series of high-voltage LDO regulators designed for noise-sensitive environments. The series offers various fixed output voltages including 1.8 V, 2.5 V, 3.3 V, and 5.0 V options. The AP7372-33CBA6-7 specifically targets applications requiring stable regulation from higher voltage rails down to standard logic levels.
The typical PSRR is 90 dB at 10 kHz.
The AP7372-33CBA6-7 is a fixed-output variant providing 3.3 V. Adjustable versions are available within the broader AP7372 family.
