Detailed Description for TLV73333PDQNR
Product Overview
Texas Instruments TLV73333PDQNR is a positive fixed-output linear voltage regulator IC that provides a single 3.3 V rail from an input voltage up to 5.5 V. The device is rated for 300 mA of output current and specifies a maximum dropout voltage of 0.27 V at 300 mA. A 60 µA quiescent current and power-supply rejection of 68 dB to 28 dB from 100 Hz to 100 kHz are provided, while an enable control and protection features including over current, over temperature, short circuit, and under-voltage lockout support regulated operation. The regulator uses a 4-X2SON (1x1) surface-mount package with an exposed pad and is specified for operation from -40°C to 125°C junction temperature.
Key Features
- Single positive fixed 3.3 V output regulator rated for 300 mA output current
- Maximum input voltage of 5.5 V
- Maximum dropout voltage of 0.27 V at 300 mA
- Quiescent current of 60 µA
- Power-supply rejection ratio of 68 dB to 28 dB from 100 Hz to 100 kHz
- Enable control feature
- Protection features include over current, over temperature, short circuit, and under-voltage lockout
- Operating temperature range of -40°C to 125°C junction temperature
- 4-X2SON (1x1) surface-mount package with exposed pad
Applications
- 3.3 V supply rail for embedded boards
- Battery-powered devices requiring a fixed 3.3 V output with enable control
- Sensor modules requiring a regulated 3.3 V rail
Design & Procurement Notes
When selecting this regulator, verify that the available input voltage remains at or below 5.5 V and that the load current does not exceed 300 mA. The 0.27 V dropout specification at 300 mA means the input rail must provide sufficient headroom above 3.3 V to maintain regulation under full load. The enable control can be used to manage output operation, and the 60 µA quiescent current is relevant for designs where standby power is a consideration. The exposed-pad 4-X2SON (1x1) package requires a surface-mount pad layout that accommodates the thermal pad, and thermal design should account for the -40°C to 125°C junction temperature range. Order the exact part number TLV73333PDQNR to ensure the fixed 3.3 V output, enable control, and package match the design.
