The TC33269-3.3VOA from Microchip Technology is a fixed 3.3V low dropout regulator capable of delivering up to 800mA. It features a dropout voltage of 1.35V at full load and a quiescent current of 8 mA. The 8-SOIC package provides a practical solution for medium-power applications. This LDO is suitable for a wide range of consumer and industrial electronics requiring a stable 3.3V rail.
- High Current Capacity: 800mA output supports power-hungry digital loads.
- Simple Fixed Output: 3.3V fixed output eliminates the need for external resistors.
- Wide Input Compatibility: Accepts inputs from 3.3V to 12V, offering design flexibility.
- Standard Package: 8-SOIC is widely available and easy to solder in production.
High-Current 3.3V Logic Supplies
With 800mA output capability, this LDO can power multiple 3.3V logic ICs, FPGAs, or microcontrollers in embedded systems.
Post-Buck Regulation
It can be used after a buck converter to provide a clean, low-noise 3.3V rail for analog and mixed-signal circuits, reducing switching noise.
Industrial Sensor Boards
The 8-SOIC package and 800mA current are suitable for powering multiple industrial sensors and their signal conditioning circuits.
Networking Equipment
Provides stable 3.3V for Ethernet PHYs, switches, and routers, with enough margin for transient loads.
Battery-Powered Devices
Although quiescent current is higher (8mA), it is suitable for devices with moderate standby requirements, such as portable testers.
LED Driver Bias Supplies
Can power the control logic and bias circuits for LED drivers, ensuring consistent 3.3V operation.
