Detailed Description for TLV733285PDQNR
Product Overview
The TLV733285PDQNR from Texas Instruments is a positive fixed 2.85 V linear voltage regulator IC with one output and a 300 mA rated current. It accepts inputs up to 5.5 V, has a maximum dropout of 0.29 V at 300 mA, and includes enable control plus over current, over temperature, short circuit, and under voltage lockout protection. Quiescent current is 60 µA, and PSRR is 68 dB to 28 dB from 100 Hz to 100 kHz. It operates over a junction temperature range of -40°C to 125°C and uses a surface-mount 4-XDFN exposed-pad package, also described as 4-X2SON (1x1).
Key Features
- Positive fixed 2.85 V single-output linear regulator rated for 300 mA
- Maximum input voltage of 5.5 V and dropout voltage of 0.29 V at 300 mA
- Enable control feature and protection for over current, over temperature, short circuit, and UVLO
- Quiescent current of 60 µA
- PSRR of 68 dB to 28 dB from 100 Hz to 100 kHz
- Surface-mount 4-XDFN exposed-pad package, also described as 4-X2SON (1x1)
- Junction temperature operating range of -40°C to 125°C
Applications
- Regulating a fixed 2.85 V rail for logic or analog circuit blocks from inputs up to 5.5 V.
- Using the enable function for controlled output activation or deactivation in compact circuit-board layouts.
- Providing a regulated supply in space-constrained surface-mount designs with an exposed-pad package.
Design & Procurement Notes
When using this regulator, confirm that the input voltage does not exceed 5.5 V and that the load current remains at or below 300 mA. The 0.29 V maximum dropout at 300 mA should be included in supply margin calculations when the input is near the 2.85 V output. The enable control can support local activation or deactivation, but the external control circuitry should be designed for the intended application. The 4-XDFN exposed-pad package requires a compatible surface-mount footprint and should be evaluated for board layout and soldering process compatibility. Because the temperature range is specified for junction temperature, thermal design should keep the junction within -40°C to 125°C under actual conditions. PSRR is specified from 100 Hz to 100 kHz, so input filtering and output noise requirements should be reviewed for loads where supply noise is a design concern.
