Key Features
- Fixed 3.3 V regulated output at up to 150 mA load with only 1.3 V typical dropout voltage
- Wide input voltage range of 5.3 V to 28 V supporting battery, automotive, and industrial supply rails
- Tiny SOT-23-5 package requiring minimal PCB area with enable pin for power sequencing control
Applications
MCP1804T-3302I/OT is well suited for always-on 3.3 V rails in IoT sensor nodes, portable instruments, and battery-powered handheld devices where the 28 V input range accommodates varying battery voltages. Its low 1.3 V dropout voltage extends battery run time in single-cell or dual-cell lithium applications. The enable pin also supports controlled power sequencing in multi-rail embedded systems.

Frequently Asked Questions
What input voltage range can MCP1804T-3302I/OT handle reliably?
MCP1804T-3302I/OT accepts an input voltage range of 5.3 V to 28 V, with an absolute maximum of 30 V. This wide range makes it compatible with 12 V, 15 V, and 24 V industrial supply rails as well as unregulated battery packs without an additional pre-regulator stage.
How does the 1.3 V typical dropout voltage of MCP1804T-3302I/OT benefit battery-powered designs?
With a typical dropout of 1.3 V at 150 mA output current, MCP1804T-3302I/OT can maintain a stable 3.3 V output from a supply as low as 4.6 V, extending usable battery life in 4-AA or lithium-ion powered devices compared to regulators needing 2 V or more of headroom.
Which compact applications benefit most from the SOT-23-5 package of MCP1804T-3302I/OT?
The 5-pin SOT-23-5 package occupies roughly 3 mm x 3 mm of PCB area, making MCP1804T-3302I/OT ideal for wearable electronics, miniature sensor modules, and space-constrained PCB designs where a TO-92 or SO-8 regulator would consume too much board space.
Can MCP1804T-3302I/OT be used in automotive 12 V systems?
Yes. MCP1804T-3302I/OT supports input voltages up to 28 V and can tolerate transients to 30 V, covering typical automotive 12 V rail variations from 9 V to 16 V. The fixed 3.3 V output at 150 mA suits microcontroller and CAN transceiver supply rails in body electronics modules.
