Product details
Overview
TPS7A2633DRVR from Texas Instruments is a 500-mA, 18-V input ultra-low quiescent current (2.0 µA) adjustable-output LDO linear voltage regulator with open-drain power-good (PG) output, 1% output accuracy over –40°C to +125°C, and 590 mV max dropout at full load - designed for battery-powered home automation, smart metering, and portable power tools.
For engineers reviewing the TPS7A2633DRVR datasheet, TPS7A2633DRVR pinout, TPS7A2633DRVR application, or TPS7A2633DRVR equivalent, key selection factors include its 1.24–17.4 V adjustable output range, stability with ≥1-µF COUT, thermal shutdown/overcurrent protection, and WSON-6 package compatibility with space-constrained PCB layouts.
Technical Context
The TPS7A2633DRVR implements a CMOS-based pass transistor architecture with feedback-controlled error amplifier referenced to a precision 1.24 V bandgap. Its UVLO circuit (2.15 V rising threshold, 70 mV hysteresis) ensures clean startup, while active overshoot pulldown prevents output voltage spikes during load transients.
Power-good functionality uses an open-drain PG output with 96.5% VOUT rising threshold and 3% hysteresis, enabling system-level reset coordination via external pull-up. Thermal shutdown activates at 165°C with 20°C hysteresis, and current limiting provides brickwall protection up to 970 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.4 V to 18 V - supports multicell Li-ion, 12-V rail, and industrial supply inputs without pre-regulation. |
| Quiescent Current | 2.0 µA - enables >10-year battery life in always-on IoT sensors with 200-mAh coin cells. |
| Output Accuracy | ±1% over temperature - ensures stable MCU core/reference voltage under thermal stress. |
| Max Dropout Voltage | 590 mV at 500 mA - allows 5.0 V output from 5.7 V input with 87.7% efficiency. |
| PG Threshold | 96.5% VOUT rising, 3% hysteresis - delivers reliable system reset without false triggering during brownouts. |
| Stability Capacitor | ≥1 µF ceramic COUT - eliminates need for large tantalum or electrolytic capacitors, reducing BOM cost and footprint. |
| Operating Temp | –40°C to +125°C junction - qualified for industrial motor drives and white goods ambient environments. |
Pinout & Package
TPS7A2633DRVR is housed in a thermally enhanced 6-pin WSON package (2.00 mm × 2.00 mm), with exposed thermal pad recommended to be connected to ground for optimal thermal performance (RθJB = 38.3°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable VOUT set by external R1/R2 feedback network; requires ≥1 µF ceramic capacitor to GND for stability. |
| FB (Pin 2) | Feedback input | Connects to voltage divider between OUT and GND to program output from 1.24 V to 17.4 V; 10 nA bias current minimizes divider error. |
| PG (Pin 3) | Open-drain power-good | Asserts low when VOUT falls below 90% VOUT; requires external pull-up to OUT or another rail for system reset signaling. |
| EN (Pin 4) | Enable control | Active-high logic input; device enabled when VEN > 0.9 V, disabled when VEN < 0.4 V; tie to VIN if always-on operation required. |
| GND (Pin 5) | Ground reference | Primary return path for IN, OUT, FB, EN, and PG; must be low-impedance connection to minimize noise and thermal resistance. |
| IN (Pin 6) | Input supply | Accepts 2.4–18 V input; requires ≥1 µF ceramic capacitor placed adjacent to IN/GND pins to suppress high-frequency ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 2.0 µA quiescent current enables multi-year operation in energy-harvesting and battery-backed applications. |
| Adjustable Output | 1.24 V to 17.4 V range via external resistors - supports diverse MCU, sensor, and analog subsystem voltages from single BOM variant. |
| Overshoot Pulldown | Active circuit clamps output overshoot during fast load release - eliminates need for external TVS or clamp diodes in portable tools. |
| UVLO with Hysteresis | 2.15 V rising / 2.09 V falling thresholds prevent oscillation during marginal input conditions in smart grid meters. |
| Thermal Protection | 165°C shutdown with 20°C hysteresis - protects against sustained overload in enclosed motor drive enclosures without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A2533DRVR | Lower IQ (1.4 µA), lower max IOUT (300 mA), same 18-V input, no PG output. | Lacks power-good signaling; unsuitable for systems requiring coordinated reset or fault reporting. | Select when PG is unnecessary and load current ≤300 mA to maximize battery life. |
| MCP1826T-3302E/DB | Fixed 3.3-V output, 500-mA rating, 2.5-µA IQ, no PG, different pinout (SOT-223). | Not adjustable; requires separate BOM for each output voltage; larger footprint than WSON-6. | Choose for cost-sensitive, fixed-voltage designs where board area and adjustability are secondary concerns. |
Compared with TPS7A2633DRVR, TPS7A2533DRVR trades PG functionality and output current for lower IQ, while MCP1826T-3302E/DB offers fixed 3.3 V in a legacy package but lacks both adjustability and power-good - making TPS7A2633DRVR the only option supporting programmable voltage, system reset, and high-density layout in one device.

FAQ
What output voltage range does the TPS7A2633DRVR support?
The TPS7A2633DRVR supports an adjustable output voltage range of 1.24 V to 17.4 V, set using external feedback resistors R1 and R2 connected to the FB pin. This range is confirmed in the Electrical Characteristics table and applies specifically to the adjustable version (DRV package), which includes TPS7A2633DRVR. Fixed-output variants are separate part numbers.
Does the TPS7A2633DRVR require an external pull-up resistor on the PG pin?
Yes, the TPS7A2633DRVR PG pin is open-drain and requires an external pull-up resistor - typically to the OUT rail or another compatible voltage source. The datasheet specifies a 10-kΩ pull-up for threshold characterization, and omitting it prevents proper power-good assertion during normal operation of the TPS7A2633DRVR.
Can the TPS7A2633DRVR operate stably with only 1 µF output capacitance?
Yes, the TPS7A2633DRVR is explicitly characterized and specified for stable operation with ≥1 µF ceramic output capacitance, as stated in both the Features list and Recommended Operating Conditions table. This eliminates the need for larger, less reliable capacitor types and reduces solution size - a verified design requirement for the TPS7A2633DRVR.
What is the maximum dropout voltage of the TPS7A2633DRVR at full load?
The maximum dropout voltage of the TPS7A2633DRVR is 590 mV at 500 mA output current and TJ = 125°C, per the Electrical Characteristics table. This value defines the minimum headroom required between input and output to maintain regulation under worst-case thermal and load conditions for the TPS7A2633DRVR.
How does the enable function work on the TPS7A2633DRVR?
The TPS7A2633DRVR EN pin is active-high: the regulator enables when VEN exceeds 0.9 V (typical) and disables when VEN drops below 0.4 V (typical). If unused, EN must not be left floating - it should be tied to IN for always-on operation, as specified in the Pin Functions table for the TPS7A2633DRVR.
