Product details
Overview
TPS76050DBVT from Texas Instruments is a 50-mA, fixed 5.0-V output low-dropout linear regulator in a 5-pin SOT-23 package, featuring 120 mV typical dropout at full load, <1 µA shutdown current, thermal shutdown, and –40°C to 125°C operating junction temperature - deployed in battery-powered microcontroller power rails and portable sensor nodes.
For engineers reviewing the TPS76050DBVT datasheet, TPS76050DBVT pinout, TPS76050DBVT application, or TPS76050DBVT equivalent, this page delivers verified electrical specs, terminal functions, real-world use cases, and validated alternative parts for low-power LDO selection in space-constrained, thermally demanding designs.
Technical Context
The TPS76050DBVT uses a BiCMOS process to achieve ultra-low quiescent current (100–1200 µA across 0–50 mA load) while maintaining tight output voltage regulation (±1% over load/temperature). Its internal current-limit and thermal-sense circuitry enable robust fault protection without external components.
It integrates an enable input (EN) with logic-level thresholds (VIH ≥ 2 V, VIL ≤ 0.8 V), supports output capacitor ESR between 0.1 Ω and 20 Ω, and requires minimum 2.2 µF ceramic or tantalum output capacitance for loop stability - all specified for operation with input voltages as low as 5.2 V (for 5-V output).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±1% (4.95–5.05 V at 25°C, 4.89–5.1 V over full load/temp) |
| Max Output Current | 50 mA continuous - sufficient for MCU cores, RF transceivers, and analog sensors |
| Dropout Voltage | 120 mV typical at 50 mA - enables operation from single Li-ion or 2xAA cells with margin |
| Quiescent Current | 100 µA at 1 mA load; <1 µA in shutdown - extends battery life in sleep modes |
| Operating Temp Range | –40°C to +125°C junction - qualified for automotive cabin and industrial edge nodes |
| Noise & PSRR | 190 µVRMS output noise (300 Hz–50 kHz); 63 dB ripple rejection at 1 kHz |
| ESD Rating | 1.5 kV HBM - meets basic handling robustness for assembly and field environments |
Pinout & Package
TPS76050DBVT is housed in a 5-pin SOT-23 (DBV) package, 2.9 × 1.6 × 1.45 mm, tape-and-reel (250 pcs), RoHS-compliant, NIPDAU lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 5.2–16 V DC; must be decoupled with ≥0.047 µF ceramic cap near pin |
| 2 (GND) | Ground reference | Common return path for input, output, and enable; connects to PCB ground plane |
| 3 (EN) | Enable control input | Active-high logic: ≥2 V enables regulation; ≤0.8 V disables output and reduces IQ to <1 µA |
| 4 (NC) | No internal connection | Unbonded pad - must remain unconnected; no routing or copper fill required |
| 5 (OUT) | Regulated output | Delivers stable 5.0 V; requires 2.2–10 µF output capacitor with 0.1–20 Ω ESR |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low shutdown current | <1 µA enables multi-year battery life in always-on IoT endpoints |
| Thermal shutdown protection | Activates at ~160°C junction; auto-recovers below 155°C - prevents permanent damage during overload |
| Current-limit foldback | 100–135 mA peak limit with constant-current mode - protects against short-circuit without latch-up |
| Wide input voltage range | 5.2 V to 16 V supports diverse sources: Li-ion, 2S alkaline, or regulated 12-V rails |
| Low-noise output | 190 µVRMS noise ensures clean power for ADC references and RF front-ends |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76050DBVR | Same electrical specs and pinout; differs only in reel size (3000 vs 250 pcs) and packaging - identical DBV package and marking (PANI) | Preferred for high-volume production due to larger reel quantity; same thermal and electrical behavior | Select TPS76050DBVR for cost-optimized large-batch builds; TPS76050DBVT suits prototyping and low-MOQ requirements. |
| MCP1700T-5002E/TT | 30-mA max output, 1.6 µA quiescent current, SOT-23-3 package (no EN pin), 600 mV dropout at 250 mA - not pin-compatible | Lacks enable control and thermal shutdown; lower current capability limits use to simpler loads | Choose MCP1700T-5002E/TT only if enable function and 50-mA headroom are unnecessary and ultra-low IQ dominates selection. |
Compared with TPS76050DBVR, the TPS76050DBVT offers identical performance in a smaller reel format ideal for design validation; versus MCP1700T-5002E/TT, it provides higher current, integrated EN, and full thermal/current protection - critical for mission-critical embedded systems.

FAQ
What is the minimum input voltage required for stable 5-V output from the TPS76050DBVT?
The TPS76050DBVT requires a minimum input voltage of 5.2 V to maintain regulation at full 50-mA load, per its recommended operating conditions. At lighter loads, it can operate closer to the dropout threshold (e.g., 5.12 V at 10 mA), but 5.2 V ensures guaranteed performance across temperature and process variation. Input below 5.2 V risks output droop or dropout.
Does the TPS76050DBVT require an external pull-up resistor on the EN pin?
No - the TPS76050DBVT does not require an external pull-up on EN. When unused, EN must be tied directly to IN to ensure continuous operation. Leaving EN floating is prohibited and may cause erratic enable/disable behavior. The device draws only 2.5–5 µA when EN = VI, so direct connection imposes negligible load.
Can the TPS76050DBVT safely drive a 2.2-µF ceramic output capacitor?
Yes - the TPS76050DBVT is explicitly characterized and stable with 2.2 µF ceramic output capacitors (ESR 0.1–20 Ω). TI's datasheet Figure 11 confirms stable impedance profile and Figure 16 shows clean load transient response with CO = 2.2 µF. Ceramic caps are preferred for low-profile, high-reliability designs.
Is the NC pin (Pin 4) on the TPS76050DBVT electrically isolated or thermally coupled?
Pin 4 (NC) on the TPS76050DBVT is a no-connect terminal with no internal bond wire or silicon connection - it is electrically isolated and thermally passive. TI's DBV package drawing confirms it is an unpopulated pad; PCB layout should leave it unconnected with no copper pour or via to avoid unintended coupling.
What is the thermal resistance (RθJA) of the TPS76050DBVT on a standard JEDEC High-K board?
On a JEDEC High-K (2s2p) board, the TPS76050DBVT has RθJA = 180°C/W, enabling 305 mW power dissipation at TA = 70°C before reaching the 125°C max junction limit. This value assumes proper PCB copper area and internal power/ground planes - actual performance depends on layout implementation.
