What are the key features of AP7312-3333W6-7?
- Dual 3.3 V fixed-output LDO channels with only 200 mV maximum dropout voltage enable efficient regulation from Li-ion battery supplies down to 3.5 V
- 2 V to 6 V wide input voltage range accommodates single-cell Li-ion, USB, and regulated 5 V bus inputs in a single compact regulator
- 6-pin SOT-23 package replaces two discrete LDO regulators in a minimal PCB footprint for dual-rail 3.3 V power distribution
What is AP7312-3333W6-7 used for?
The AP7312-3333W6-7 is used in portable consumer electronics, IoT sensor modules, and wearable devices requiring dual 3.3 V rails from a single Li-ion cell or USB 5 V supply. Its low 200 mV dropout voltage and 6-pin SOT-23 form factor make it well-suited for Bluetooth and Wi-Fi module power circuits where two independent 3.3 V supplies must be generated with minimal board space and component count.

Frequently Asked Questions
How does the 200 mV dropout voltage of the AP7312-3333W6-7 extend battery life in Li-ion powered designs?
With a maximum dropout voltage of only 200 mV, the AP7312-3333W6-7 maintains its 3.3 V output until the Li-ion battery voltage drops to approximately 3.5 V, extracting more usable capacity from cells that would otherwise cut off at 3.6 V to 3.7 V in higher-dropout regulators. This extends runtime by 10% to 15% in typical portable device designs compared to regulators with 500 mV or greater dropout.
For a dual-rail 3.3 V design powering separate analog and digital circuits, how does the AP7312-3333W6-7 simplify the BOM?
The AP7312-3333W6-7 integrates 2 independent 3.3 V LDO channels in a single 6-pin SOT-23 package, replacing two discrete single-channel regulators and their associated decoupling capacitors. This reduces the power supply component count by at least 2 ICs and approximately 4 capacitors, saving PCB space in IoT and wearable designs where dual isolated 3.3 V rails for analog and digital domains are needed.
Can the AP7312-3333W6-7 operate directly from a USB 5 V bus while also accepting a 3.7 V Li-ion battery as an alternate input?
Yes. The AP7312-3333W6-7 accepts input voltages from 2 V to 6 V, covering both the 4.75 V to 5.25 V USB bus voltage range and the 3.0 V to 4.2 V Li-ion single-cell range. This allows the same regulator to remain in-circuit regardless of whether the system is USB-powered or battery-powered, simplifying power path design for devices with dual-input 3.3 V rail requirements.
