Product details
Overview
TPS71710DCKTG4 from Texas Instruments is a fixed-output, 1.0-V, 150-mA low-dropout linear regulator in SC-70-5 package, featuring ultra-high PSRR (70 dB at 1 kHz), low noise (30 µVRMS, 100 Hz–100 kHz), and 170 mV typical dropout at full load - designed for powering noise-sensitive analog and RF circuits in portable devices.
For engineers reviewing the TPS71710DCKTG4 datasheet, TPS71710DCKTG4 pinout, TPS71710DCKTG4 application, or TPS71710DCKTG4 equivalent, key selection criteria include output voltage accuracy (±3% over temp/load), enable-pin compatibility with TTL/CMOS logic, stability with 1-µF ceramic output capacitor, and thermal shutdown behavior at 160°C junction temperature.
Technical Context
The TPS71710DCKTG4 employs a PMOS pass device and high-gain BiCMOS error amplifier to achieve fast transient response and maintain high PSRR even at low headroom (VIN – VOUT = 1 V). Its quick-start circuit charges the NR capacitor within ~160 µs, enabling rapid power-up while preserving low-noise performance via 0.01-µF noise reduction capacitance.
It integrates undervoltage lockout (UVLO) with 2.45 V rising threshold and 150 mV hysteresis, thermal shutdown at 160°C (reset at 140°C), and internal current limiting (200–575 mA). Ground current remains stable at 45 µA (typ) under light load and rises to 100 µA at 150 mA output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0 V ±3% over –40°C to 125°C, load (0–150 mA), line (VIN ≥ 2.5 V), and process variation. |
| Max Output Current | 150 mA continuous; internal current limit activates at 200–575 mA depending on VIN and temperature. |
| Dropout Voltage | 170 mV typical at 150 mA, enabling operation from 1.17 V input - critical for single-cell Li-ion or coin-cell systems. |
| PSRR | 70 dB at 1 kHz, 67 dB at 100 kHz, 45 dB at 1 MHz (VIN – VOUT = 1 V); maintains rejection in RF-sensitive signal chains. |
| Output Noise | 30 µVRMS (100 Hz–100 kHz) with CNR = 0.01 µF; reduced further with larger NR capacitance. |
| Ground Current | 45 µA typical at IOUT = 0.1 mA; increases to 100 µA at 150 mA - optimized for battery runtime in always-on sensors. |
| Enable Threshold | VEN(high) = 1.2 V min (TTL/CMOS compatible); VEN(low) ≤ 0.4 V disables output, reducing shutdown current to ≤1.5 µA. |
Pinout & Package
TPS71710DCKTG4 is housed in a 5-pin SC-70 (DCK) package, measuring 2.00 mm × 1.25 mm × 0.95 mm, with exposed pad not present. The package supports reflow soldering per JEDEC J-STD-020 and is rated for operation from –40°C to 125°C junction temperature.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply connection | Accepts 2.5 V to 6.5 V; requires 0.1–1 µF ceramic bypass capacitor close to pin for stability and PSRR optimization. |
| 2 (GND) | Power ground reference | Low-impedance return path for IN, OUT, EN, and NR; must be connected directly to PCB ground plane. |
| 3 (EN) | Active-high enable control | Drives high (>1.2 V) to activate regulator; pulls low (<0.4 V) to enter shutdown mode with <1.5 µA quiescent current. |
| 4 (NR) | Noise reduction filter node | Connects to 0.01 µF ceramic capacitor to suppress bandgap reference noise; enables 30 µVRMS output noise performance. |
| 5 (OUT) | Regulated output terminal | Delivers 1.0 V ±3%; requires ≥1 µF ceramic output capacitor (X5R/X7R) for loop stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise regulation | 30 µVRMS (100 Hz–100 kHz) with 0.01 µF NR capacitor - meets stringent requirements for camera sensor analog front-ends. |
| High PSRR at RF frequencies | 67 dB at 100 kHz and 45 dB at 1 MHz enables clean power delivery to Bluetooth®/Wi-Fi RF sections without additional filtering. |
| Fast startup with noise control | Quick-start circuit charges NR capacitor in ~160 µs, achieving 90% VOUT in <1 ms while preserving low-noise operation. |
| Stable at zero load | Active low-current mode maintains loop gain down to 0 mA output - eliminates need for minimum load resistors in standby systems. |
| Robust protection suite | Integrated thermal shutdown (160°C trip), current limiting, and UVLO (2.45 V rising) ensure safe operation under fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, low-dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS71710DCKR | Same electrical specs and SC-70-5 package; G4 suffix indicates green (Pb-free) and RoHS-compliant finish; DCKR is standard RoHS version without enhanced marking. | No functional difference; both qualified for industrial temp range (–40°C to 125°C) and identical thermal performance. | Select TPS71710DCKTG4 when compliance documentation (e.g., IPC-1752, REACH) requires explicit G4-grade material traceability. |
| MCP1801T-1002I/OT | 1.0-V fixed LDO in SOT-23-5; 180 mA max, 200 mV dropout, 45 µVRMS noise, but only 40 dB PSRR at 100 kHz and no NR pin. | Lacks noise-reduction capability and delivers lower PSRR - unsuitable for RF-coupled or high-SNR analog systems. | Choose only for cost-sensitive, non-RF applications where 40 dB PSRR and 45 µVRMS noise are acceptable. |
Compared with TPS71710DCKR, the TPS71710DCKTG4 offers identical performance with enhanced environmental compliance; versus MCP1801T-1002I/OT, it provides superior noise suppression, higher PSRR across frequency, and integrated NR functionality - justifying use in precision analog and wireless coexistence designs.

FAQ
What is the maximum input voltage rating for the TPS71710DCKTG4?
The TPS71710DCKTG4 has an absolute maximum input voltage of 7 V, but its recommended operating range is 2.5 V to 6.5 V. Operation above 6.5 V risks permanent damage, and below 2.5 V may prevent regulation due to dropout constraints - especially critical since the device requires VIN ≥ VOUT + VDO (≥1.17 V) to maintain 1.0-V output.
Does the TPS71710DCKTG4 require an external capacitor on the NR pin?
Yes - the TPS71710DCKTG4 requires a 0.01-µF ceramic capacitor between NR and GND to achieve its specified 30 µVRMS output noise. Omitting this capacitor increases noise to ~95×VOUT (≈95 µVRMS), and using >0.01 µF delays startup time beyond the quick-start window, degrading turn-on performance.
Can the TPS71710DCKTG4 operate without any load connected to the OUT pin?
Yes - the TPS71710DCKTG4 is explicitly designed to remain stable and regulated at zero load. Its internal low-current mode maintains loop gain under no-load conditions, eliminating the need for a minimum load resistor - a key advantage over legacy PMOS LDOs that require ≥1 mA load for stability.
What is the thermal shutdown behavior of the TPS71710DCKTG4?
The TPS71710DCKTG4 triggers thermal shutdown at approximately 160°C junction temperature and resets at ~140°C. This hysteresis prevents oscillation near trip point. Continuous cycling indicates inadequate PCB copper area or excessive power dissipation - design margin should keep TJ ≤125°C under worst-case ambient and load conditions.
Is the TPS71710DCKTG4 pin-compatible with other TPS717xx variants in SC-70-5?
Yes - all TPS717xx devices in the DCK (SC-70-5) package share identical pinout: Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = NR, Pin 5 = OUT. Voltage variants (e.g., TPS71712, TPS71715) are functionally interchangeable at the board level, provided input/output voltage ranges and load requirements align.
