Product Details
TPS7A2050PDBVR - 5.0 V, 300 mA Low-Noise LDO
Texas Instruments TPS7A2050PDBVR is a fixed 5.0 V, 300 mA low-dropout linear regulator in a 5-pin SOT-23 DBV package, cataloged as SC-74A / SOT-753.
Electrical limits, pin functions, package, and orderable status were checked against the TI TPS7A20 Rev. H datasheet and exact part-detail page.
Overview
TPS7A2050PDBVR combines a fixed 5.0 V output with low noise, low quiescent current, high power-supply rejection, controlled startup, enable control, and automatic output discharge. The device is intended for noise-sensitive analog and RF rails as well as battery-powered equipment.
Key Advantages
Low-noise supply rail
7 microvolts RMS typical output noise supports sensitive analog signal chains.
High PSRR
Typical rejection reaches 95 dB at 1 kHz under the stated light-load condition.
Low operating current
6.5 microamps typical ground current at no load helps reduce standby power.
Compact implementation
The DBV SOT-23-5 package and 1 microfarad ceramic capacitors enable a small solution.
Feature Summary
300 mA output
Designed to source up to 300 mA over the recommended operating range.
Precision regulation
Maximum output tolerance is plus or minus 1.5 percent over line, load, and temperature for this DBV voltage option.
Smart enable
An internal pulldown holds the regulator disabled when EN is left floating.
Protection and discharge
Current limiting, thermal shutdown, soft-start, and an output-discharge pulldown support controlled operation.
Package & Footprint
TI specifies the exact orderable part in the 5-pin SOT-23 DBV package, nominally 2.9 mm by 2.8 mm including pins. The catalog's SC-74A and SOT-753 names refer to this five-lead package family; the registered package image uses SC-74A.
- Use TI's DBV mechanical drawing and top-view numbering.
- Place input and output capacitors close to their pins and ground.
- Use a low-impedance ground return for both capacitors.
- Confirm thermal performance for the actual copper layout and ambient conditions.
The registered JPG is checked locally and at the production URL before publication.
Pin Functions
The DBV SOT-23 assignment follows the TI top-view diagram.
Do not infer pin order from another five-lead LDO; verify DBV top-view orientation on the PCB footprint.
Key Specifications

|---|---|
| Regulator type | Fixed positive low-dropout linear regulator |
| Nominal output | 5.0 V |
| Recommended input supply | 1.6 V to 6.0 V family range; the 5.0 V option requires appropriate output headroom |

| Output tolerance | plus or minus 1.5 percent maximum; DBV, 5.3 V to 6.0 V input, 1 mA to 300 mA |
| Dropout voltage | 145 mV maximum at 300 mA for DBV options from 2.5 V to below 5.5 V output |

| Shutdown current | 0.07 microamps typical, 0.2 microamps maximum at 25 degrees C |
| Output noise | 7 microvolts RMS typical, 10 Hz to 100 kHz, stated 2.8 V test condition |
| Power-supply rejection | 95 dB typical at 1 kHz and 20 mA under the stated condition |
| Capacitors | 1 microfarad nominal input; 1 to 200 microfarads output, with effective 0.47 microfarad minimum for stability |
| Operating junction temperature | -40 degrees C to +125 degrees C |
| Junction-to-ambient thermal resistance | 187.1 degrees C/W reference value for DBV |
| Package | 5-pin SOT-23 DBV / SC-74A / SOT-753; 3000-piece large tape and reel |
Typical values are not guaranteed limits. Apply the exact test conditions and derating guidance from the current TI datasheet.
Replacement Considerations
Any replacement must match the fixed 5.0 V output, 300 mA load requirement, DBV footprint and IN/GND/EN/N.C./OUT pin order, enable thresholds, automatic discharge behavior, dropout, output accuracy, capacitor stability range, noise, PSRR, temperature rating, and tape-and-reel form. A different TPS7A20 voltage suffix is not a direct substitute.
No internal replacement link is asserted without an exact API-confirmed catalog match and engineering review.
Manufacturer Information
Texas Instruments lists TPS7A2050PDBVR as an active production part. The exact orderable uses the DBV SOT-23 package with five pins, operates from -40 degrees C to +125 degrees C, ships in 3000-piece large tape and reel, and carries part marking 2B1F.
Applications
RF and analog rails
Provide a low-noise supply for sensitive signal-chain circuitry.
Portable equipment
Support battery-powered cameras, medical devices, and wearables.
Industrial sensing
Regulate rails in smart meters, field transmitters, and control electronics.
Post-regulation
Reduce switching-supply noise where input headroom and dissipation allow.
Quality & Authenticity
Verify the full TPS7A2050PDBVR order code, 2B1F package marking, DBV dimensions, reel label, moisture-sensitivity information, lead finish, and lot traceability during incoming inspection. Package appearance alone does not establish authenticity.
FAQ
What output does TPS7A2050PDBVR provide?
It is the fixed 5.0 V, 300 mA DBV member of the TPS7A20 family.
Can EN be left floating?
The smart internal pulldown holds the LDO disabled when EN floats; drive EN high to enable the output.
What output capacitor is required?
TI specifies 1 to 200 microfarads nominal output capacitance, with at least 0.47 microfarad effective capacitance for stability.
Does the device discharge the output?
Yes. A typical 150-ohm internal pulldown discharges OUT when the regulator is disabled.
Is every SOT-23-5 LDO pin-compatible?
No. Confirm the exact IN, GND, EN, N/C, and OUT arrangement before substitution.
Engineering Notice
Verify worst-case input headroom, load and line tolerance, capacitor effective value across bias and temperature, startup timing, thermal rise, and EN behavior in the final design. For a 5.0 V output, the available input range above the output is narrow because the recommended maximum input is 6.0 V.
