Detailed Description for TLV73328PDQNR3
Product Overview
The Texas Instruments TLV73328PDQNR3 is a positive fixed-output linear voltage regulator for 2.8 V single-rail supply tasks. It operates from a maximum input voltage of 5.5 V and delivers an output current of 300 mA, with a maximum dropout of 0.29 V at 300 mA. The device includes an enable control feature and protection functions for over current, over temperature, short circuit, and under voltage lockout. Quiescent current is 60 µA, and PSRR is 68 dB at 100 Hz and 28 dB at 100 kHz. It uses a surface-mount 4-XDFN exposed-pad package with a 4-X2SON (1x1) device package and a junction temperature range of -40°C to 125°C.
Key Features
- Positive fixed 2.8 V output from one regulator channel
- Maximum input voltage of 5.5 V
- Output current of 300 mA
- Maximum dropout voltage of 0.29 V at 300 mA
- Enable control feature
- Over current, over temperature, short circuit, and under voltage lockout protection
- Quiescent current of 60 µA
- PSRR of 68 dB at 100 Hz and 28 dB at 100 kHz
- Surface-mount 4-XDFN exposed-pad package with 4-X2SON (1x1) device package
- Junction temperature range of -40°C to 125°C
Applications
- Fixed 2.8 V rail generation for digital or analog circuitry within a 5.5 V input budget
- Enable-controlled local supply for circuit blocks powered on or off under system control
- Surface-mount regulation in space-limited assemblies using a 4-X2SON (1x1) package and integrated protections
- Regulating a 2.8 V supply for loads where dropout at 300 mA and PSRR across 100 Hz to 100 kHz are relevant
Design & Procurement Notes
Use this regulator when the rail is fixed at 2.8 V and load current does not exceed 300 mA. Verify that input voltage stays at or below 5.5 V and remains high enough for the 0.29 V dropout at full load. The enable feature supports controlled power sequencing, while the protections address over current, over temperature, short circuit, and under voltage lockout. Include the 60 µA quiescent current in standby power budgets and use the PSRR values when assessing ripple rejection from 100 Hz to 100 kHz. Layout should follow the 4-XDFN exposed-pad, 4-X2SON (1x1) surface-mount package, and thermal design should account for -40°C to 125°C junction temperature. Specify TLV73328PDQNR3 when documenting the fixed-output selection.
