AP7332-1218W6-7

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

The AP7332-1218W6-7 is a dual-channel low-dropout (LDO) linear voltage regulator manufactured by Diodes Incorporated. It provides fixed output voltages of 1.2 V and 1.8 V with a combined maximum output current of 300 mA per channel. The device operates within an input voltage range of 2 V to 6 V and maintains a typical power supply rejection ratio (PSRR) of 65 dB at 1 kHz. Quiescent current is specified at 60 µA, ensuring efficient operation in battery-powered applications. The regulator features a U-WLB1012-6 package and supports surface-mount installation.

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

Verify the specific suffix W6-7 confirms the SOT-26-6 packaging and tape-and-reel quantity when ordering. Confirm RoHS compliance status through the manufacturer's official documentation prior to integration. Ensure the supplier source is authorized to guarantee component authenticity and traceability for quality assurance purposes.

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

Select this component when two distinct regulated voltages are required from a single package to minimize board space. The 65 dB PSRR makes it suitable for filtering noise from unregulated sources. Verify that the input voltage remains within the 2 V to 6 V window to maintain regulation. Consider the 60 µA quiescent current impact on total system standby power requirements.
