AP7332-2833W6-7

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

The AP7332-2833W6-7 is a dual-channel low-dropout (LDO) linear voltage regulator manufactured by Diodes Incorporated. It integrates two independent positive regulators within a single SOT-26-6 surface-mount package. The device provides fixed output voltages of 2.8 V and 3.3 V, with each channel capable of delivering up to 300 mA of output current. It operates from an input voltage range of 2 V to 6 V and maintains a typical quiescent current of 60 uA. Key performance specifications include a typical power supply rejection ratio (PSRR) of 65 dB at 1 kHz and a maximum dropout voltage of 400 mV. The component supports an operating temperature range from -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix W6-7 against official Diodes Incorporated documentation to confirm the exact pinout and packaging configuration. Ensure that the required output voltages of 2.8 V and 3.3 V align with your system design before procurement. Cross-reference the datasheet for thermal dissipation limits under your specific load conditions to prevent overheating.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a dual-output LDO solution is required to save board space compared to using separate single-channel regulators. Consider the 300 mA per channel limit to ensure it meets the peak current demands of both loads. Evaluate the 65 dB PSRR requirement against the noise sensitivity of your downstream components to determine if additional filtering is necessary.
