Product details
Overview
TPS76032DBVTG4 from Texas Instruments is a 50-mA low-dropout linear regulator with fixed 3.2-V output, 120-mV typical dropout at full load, <1-µA quiescent current in shutdown, thermal protection, and operation from –40°C to 125°C. It delivers stable voltage regulation for battery-powered microcontrollers, portable sensors, and low-power IoT edge nodes.
For engineers reviewing the TPS76032DBVTG4 datasheet, TPS76032DBVTG4 pinout, TPS76032DBVTG4 application, or TPS76032DBVTG4 equivalent, key selection criteria include dropout performance at 50 mA, shutdown current below 1 µA, SOT-23 package thermal resistance (RθJA = 180–259 °C/W), and enable-input logic thresholds (0.8 V low / 2 V high).
Technical Context
The TPS76032DBVTG4 uses a BiCMOS process to achieve ultra-low quiescent current and tight output voltage tolerance (±1.25% over load/temperature). Its internal architecture integrates current limiting, thermal shutdown, and an enable-controlled pass transistor with built-in reverse-current diode.
It requires a minimum 2.2-µF output capacitor with ESR between 0.1 Ω and 20 Ω for loop stability, and supports input voltages from 3.4 V to 16 V. The EN pin provides active-high logic control with sub-1-µA standby draw when pulled low.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.2 V ±1.25% over 1–50 mA load and –40°C to 125°C |
| Max output current | 50 mA continuous; current-limited to 100–135 mA peak |
| Dropout voltage | 120 mV typical at 50 mA - enables regulation from 3.32 V input |
| Quiescent current | 170 µA typical at 1 mA load; drops to <1 µA in shutdown mode |
| Input voltage range | 3.4 V to 16 V - supports single-cell Li-ion (4.2 V) and multi-cell alkaline inputs |
| Ripple rejection | 63 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters |
| ESD rating | 1.5 kV HBM - meets basic handling robustness for board assembly |
Pinout & Package
SOT-23 (DBV) 5-pin surface-mount package, 1.45 mm max height, JEDEC MO-178 compliant, tape-and-reel delivery (250 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 3.4–16 V; requires ≥0.047 µF ceramic decoupling near pin |
| 2 (GND) | Ground reference | Common return path for input, output, and enable circuits |
| 3 (EN) | Enable control input | Active-high logic: <0.8 V disables regulator (<1 µA IQ); >2 V enables |
| 4 (NC) | No internal connection | Unbonded pad - must remain unconnected on PCB |
| 5 (OUT) | Regulated output | Delivers 3.2 V ±1.25%; 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 long-term battery hold-up in sleep-mode systems |
| Thermal shutdown protection | Activates at 160°C junction temperature; auto-recovers at 155°C |
| Low-noise output | 190 µVrms (300 Hz–50 kHz) - suitable for analog sensor front-ends |
| Stable with small capacitors | Works with standard 2.2 µF tantalum or ≥2.5 µF ceramic caps - reduces BOM count |
| Reverse-current blocking diode | Integrated IN-to-OUT diode limits reverse current to ≤100 mA - prevents backfeed in multi-rail systems |
Applications
| Wearable Health Monitor | Industrial Wireless Sensor Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76032DBVR | Same silicon, 3000-piece tape-and-reel vs. 250-piece reel; identical electrical specs and marking (PAOI) | No functional difference - differs only in packaging quantity and reel size | Select DBVR for high-volume production; DBVTG4 for prototyping or low-MOQ orders |
| MCP1700T-3202E/TT | 250-mA rated, 6-µA quiescent current (active), no enable pin, ±2% output tolerance | Lacks enable control and tighter 3.2-V accuracy; higher IQ makes it unsuitable for deep-sleep systems | Use only where enable functionality is unnecessary and 6-µA active IQ is acceptable |
Compared with TPS76032DBVTG4, TPS76032DBVR offers identical performance in larger reels, while MCP1700T-3202E/TT trades enable control and precision for higher output current and lower active quiescent current - making it viable only in non-shutdown applications requiring >50 mA.

FAQ
What is the maximum input voltage rating for the TPS76032DBVTG4?
The TPS76032DBVTG4 has an absolute maximum input voltage of 16 V. Its recommended operating input range is 3.4 V to 16 V, enabling compatibility with single-cell Li-ion (up to 4.2 V), dual-cell alkaline (up to 3.2 V nominal, 3.6 V fresh), and higher-voltage industrial rails. Exceeding 16 V risks permanent damage per the absolute maximum ratings table.
Does the TPS76032DBVTG4 require an external capacitor on the EN pin?
No, the TPS76032DBVTG4 does not require an external capacitor on the EN pin. The enable input is CMOS-compatible with low leakage (<1 µA), and TI's datasheet specifies only that EN must not be left floating - it should be tied to IN (for always-on operation) or driven by a clean logic signal. Adding capacitance could slow enable/disable transitions and is not recommended unless intentional filtering is needed.
Can the TPS76032DBVTG4 be used without the NC pin connected?
Yes - pin 4 (NC) on the TPS76032DBVTG4 is explicitly designated "No internal connection" in the datasheet and functional diagram. It must remain unconnected on the PCB layout. No copper trace, solder mask opening, or thermal pad should contact this pin, as it serves no electrical function and bonding wire is absent.
What is the output voltage tolerance of the TPS76032DBVTG4 over temperature and load?
The TPS76032DBVTG4 maintains output voltage within ±1.25% of 3.2 V across the full operating junction temperature range (–40°C to 125°C) and load current range (1 mA to 50 mA), as specified in the electrical characteristics table. At 25°C and 1 mA, tolerance tightens to ±1.25% (3.16–3.24 V); worst-case variation across conditions remains bounded per datasheet limits.
Is the TPS76032DBVTG4 RoHS-compliant and lead-free?
Yes, the TPS76032DBVTG4 is RoHS-compliant and features a NIPDAU (nickel-palladium-gold) lead finish, as confirmed in TI's official Packaging Information addendum. It carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and meets JEDEC J-STD-020 reflow requirements up to 260°C peak.
