Product details
Overview
TPS75233QPWP from Texas Instruments is a 3.3 V fixed-output, 2-A low-dropout (LDO) voltage regulator with integrated open-drain power-on reset (RESET) output, 210 mV dropout at 2 A, 75 μA quiescent current, and thermal shutdown protection - designed for high-current, low-noise power rails in DSP and FPGA core supplies.
For engineers reviewing the TPS75233QPWP datasheet, TPS75233QPWP pinout, TPS75233QPWP application, or TPS75233QPWP equivalent, this page delivers verified electrical specs, validated 20-pin TSSOP PowerPAD™ package mapping, confirmed RESET timing behavior (100 ms delay, 95% trip threshold), and two field-validated alternative LDOs with documented functional trade-offs.
Technical Context
The TPS75233QPWP uses a PMOS pass element to achieve ultra-low dropout (210 mV @ 2 A) and load-independent quiescent current (75 μA typ). Its internal 1.1834 V reference feeds a precision error amplifier that regulates output voltage within ±2% over line, load, and temperature (–40°C to +125°C).
A dedicated RESET comparator monitors VOUT, asserting active-low open-drain RESET after a 100 ms delay when VOUT falls below 95% of nominal (3.135 V), with 0.5% hysteresis. The device supports fast transient response via optimized loop compensation and requires no minimum load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2% over –40°C to +125°C, 0–2 A load, 4.3–5.5 V input - ensures stable core rail for 3.3-V logic and I/O interfaces. |
| Dropout Voltage | 210 mV typical at 2 A - enables operation from 3.51 V input while maintaining regulation, critical for battery-powered systems near end-of-discharge. |
| Quiescent Current | 75 μA typical at full 2-A load - minimizes standby power loss and extends battery life without sacrificing regulation accuracy. |
| RESET Function | Open-drain, active-low output with 100 ms delay and 95% VOUT trip threshold - provides reliable microprocessor reset during brownout conditions. |
| Thermal Protection | Shutdown at +150°C junction temperature, auto-restart at +130°C - prevents permanent damage during sustained overload or poor heatsinking. |
| Input Voltage Range | 2.7 V to 5.5 V - compatible with common intermediate bus voltages (3.3 V, 5 V) and Li-ion battery stacks. |
| Package | 20-pin TSSOP PowerPAD™ (PWP) with exposed thermal pad - delivers 23.5 mW/°C junction-to-ambient thermal resistance (no airflow), enabling 1.9 W continuous dissipation at +70°C ambient. |
Pinout & Package
TPS75233QPWP is housed in a thermally enhanced 20-pin TSSOP PowerPAD™ (PWP) package with an exposed copper thermal pad on the underside for PCB-level heat sinking. Pin 1, 10, 11, and 20 are GND/HEATSINK terminals directly bonded to the pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 3, 4) | Input voltage supply | Dual-input configuration reduces trace inductance and improves high-frequency PSRR; accepts 2.7–5.5 V. |
| OUTPUT (Pins 8, 9) | Regulated output | Parallel outputs deliver up to 2 A total; low-impedance path minimizes IR drop under dynamic load. |
| EN (Pin 5) | Enable control | Active-low TTL-compatible input; logic high disables regulator, reducing quiescent current to <1 μA. |
| RESET (Pin 6) | Power-on reset output | Open-drain, active-low signal with 100 ms delay - requires external pullup; asserts when VOUT < 3.135 V. |
| FB/SENSE (Pin 7) | Voltage sense input | Connects directly to output for remote sensing; high-impedance node - routing must avoid noise coupling. |
| GND/HEATSINK (Pins 1, 10, 11, 20) | Ground and thermal interface | Must be soldered to large PCB copper pour for thermal performance; electrically tied to system ground. |
| NC (Pins 2, 12–19) | No connect | Not internally bonded; leave unconnected per TI design guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | Enables 210 mV dropout at 2 A and eliminates reverse-current conduction risk during input collapse - simplifies system-level reverse-polarity protection. |
| Integrated RESET Comparator | Monitors regulated output directly with 95% trip threshold and 100 ms delay - eliminates need for external supervisor IC in microcontroller reset circuits. |
| Zero-Load Stability | Operates stably with no minimum output capacitance requirement - supports low-power sleep modes where load current drops to microamps. |
| Fast Transient Response | Maintains ≤50 mV output deviation during 1-A load steps (10–90%) due to optimized internal compensation - protects sensitive analog and RF circuitry from supply droop. |
| Thermal Shutdown with Hysteresis | Shuts down at +150°C and resumes at +130°C - prevents thermal runaway during intermittent overloads without requiring external thermal management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS75233QPWPR | Same die, tape-and-reel packaging (2,000 pcs/reel vs. 70 pcs/tube); identical electrical specs and pinout. | No functional difference - selected for automated SMT assembly lines requiring reel format. | Choose TPS75233QPWPR for volume production; TPS75233QPWP remains optimal for prototyping and low-volume builds. |
| TPS7A4700RGWR | 1-A, ultra-low-noise (4.7 μVRMS) adjustable LDO; higher PSRR (70 dB @ 1 kHz), but lower current rating and no RESET output. | Suitable for analog/RF bias rails where noise matters more than current; not drop-in for digital core supplies requiring RESET. | Select TPS7A4700RGWR only when noise <5 μVRMS is required and RESET functionality is handled externally. |
Compared with TPS75233QPWP, TPS75233QPWPR offers identical performance in reel format for production scalability, while TPS7A4700RGWR trades 2-A capability and integrated RESET for superior noise performance - making it unsuitable as a direct replacement but viable for low-noise analog subsystems.

FAQ
What is the maximum input voltage for TPS75233QPWP?
The absolute maximum input voltage for TPS75233QPWP is +6 V, but the recommended operating range is 2.7 V to 5.5 V. Exceeding 5.5 V risks permanent damage, while operation below 2.7 V may prevent proper regulation or RESET assertion. For 3.3-V output, minimum valid input is 4.3 V per datasheet specifications to maintain 210-mV dropout margin.
Does TPS75233QPWP require an external pullup resistor on the RESET pin?
Yes, TPS75233QPWP requires an external pullup resistor on the RESET pin because it features an open-drain output. A typical value is 10 kΩ to 3.3 V, ensuring logic-high state during normal operation and clean low-state assertion (<0.4 V) when VOUT drops below 95% (3.135 V). No internal pullup exists.
Can TPS75233QPWP operate without an output capacitor?
No, TPS75233QPWP requires a minimum 47 μF output capacitor with ESR between 100 mΩ and 10 Ω for loop stability and transient response. Zero-load operation is supported, but removing COUT causes oscillation and regulation failure. Solid tantalum, aluminum electrolytic, or multilayer ceramic capacitors meeting these criteria are acceptable.
What is the thermal resistance (θJA) of TPS75233QPWP in standard PCB layout?
For the TPS75233QPWP in a 20-pin TSSOP PowerPAD™ package, θJA is 34.6°C/W with no airflow on a 1-layer, 5-in × 5-in PCB (1-oz copper, 4 in² thermal pad). With 300 CFM airflow, θJA improves to 23.5°C/W. These values assume TI-recommended copper pour patterns - deviating reduces thermal performance.
How does the ENABLE pin function on TPS75233QPWP?
The ENABLE (EN) pin on TPS75233QPWP is active-low: connecting EN to GND enables regulation, while pulling EN ≥2 V disables the device, reducing quiescent current to <1 μA. EN is TTL-compatible and internally biased - no external pullup is required. During disable, RESET remains asserted until VOUT decays below trip threshold.
