Product details
Overview
TPS71713DCKR from Texas Instruments is a fixed-output, low-noise, high-PSRR linear regulator delivering 1.3 V at up to 150 mA with 170 mV typical dropout, 30 µVRMS output noise (100 Hz–100 kHz), and 70 dB PSRR at 1 kHz - deployed in camera sensor power rails and RF front-end biasing where clean, stable low-voltage supply is critical.
For engineers reviewing the TPS71713DCKR datasheet, TPS71713DCKR pinout, TPS71713DCKR application, or TPS71713DCKR equivalent, key selection criteria include ultra-low noise performance with optional NR capacitor support, SC-70-5 package footprint constraints, dropout behavior under 150 mA load, and enable logic compatibility with 1.2 V minimum high-level threshold.
Technical Context
The TPS71713DCKR employs a PMOS pass device and BiCMOS process to achieve fast startup, low ground current (45 µA typical), and stable regulation with only 1 µF ceramic output capacitance. Its error amplifier features high gain and bandwidth to sustain 70 dB PSRR at 1 kHz while maintaining ±3% output accuracy over –40°C to 125°C.
A dedicated noise reduction (NR) pin accepts a 0.01 µF capacitor to filter bandgap reference noise, reducing output noise to 12.5 × VOUT µVRMS; a quick-start circuit charges CNR within 160 µs. The device integrates undervoltage lockout (2.45 V rising threshold), thermal shutdown (160°C), and current limiting (200–575 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.3 V - eliminates external feedback resistors; supports direct connection to 1.3 V I/O domains or core logic. |
| Max Output Current | 150 mA - sufficient for image sensor analog blocks, RF transceivers, or low-power microcontroller cores. |
| Dropout Voltage | 170 mV typical at 150 mA - enables operation from 1.47 V input, critical for single-cell Li-ion or coin-cell systems. |
| PSRR | 70 dB at 1 kHz, 67 dB at 100 kHz - suppresses switching noise from DC/DC converters feeding intermediate rails. |
| Output Noise | 30 µVRMS (100 Hz–100 kHz), reduced to 16.3 µVRMS with 0.01 µF NR cap - meets stringent noise requirements of ADC references and RF LNA biasing. |
| Ground Current | 45 µA typical at light load - extends battery life in always-on sensor nodes and wearable devices. |
| Enable Threshold | VEN(HIGH) = 1.2 V min - compatible with 1.8 V or 3.3 V GPIO without level-shifting. |
Pinout & Package
TPS71713DCKR is housed in a 5-pin SC-70 (DCK) package measuring 2.00 mm × 1.25 mm, optimized for space-constrained portable electronics. Thermal performance is characterized by RθJA = 279.2°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input supply connection | Accepts 2.5 V–6.5 V; requires 0.1–1 µF ceramic bypass capacitor close to pin for stability and transient response. |
| GND (Pin 2) | Power ground reference | Primary return path for load and quiescent current; must be low-impedance and tied directly to system ground plane. |
| EN (Pin 3) | Active-high enable control | Drives high ≥1.2 V to activate regulator; pulls low ≤0.4 V to enter shutdown (ISHDN ≤1.5 µA). |
| NR (Pin 4) | Noise reduction filter node | Connects to 0.01 µF ceramic capacitor to reduce internal bandgap noise; enables 16.3 µVRMS output noise at 1.3 V. |
| OUT (Pin 5) | Regulated output | Delivers 1.3 V ±3% across load (0–150 mA), line (2.5–6.5 V), and temperature (–40°C to 125°C); requires ≥1 µF ceramic output cap. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 30 µVRMS (100 Hz–100 kHz), further reduced via NR pin - enables use in precision analog signal chains without additional filtering. |
| High PSRR at high frequency | 67 dB at 100 kHz - maintains clean output when powered from noisy switched-mode supplies in multi-rail systems. |
| Low dropout with full load | 170 mV at 150 mA - allows efficient operation from marginally higher input rails, minimizing power loss and heat generation. |
| Stable with minimal output capacitance | 1 µF ceramic capacitor sufficient for stability - reduces BOM count and PCB area vs. regulators requiring ≥10 µF. |
| Integrated protection | Thermal shutdown (160°C), current limit (200–575 mA), and UVLO (2.45 V rising) - ensures robust operation under fault conditions without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0513PDBVR | Lower IQ (25 µA), same 1.3 V fixed output, but 200 mV dropout at 150 mA and no NR pin. | Lacks noise-reduction capability; unsuitable where <20 µVRMS noise is required. | Choose for ultra-low-power sleep modes where noise is secondary to quiescent current. |
| MCP1700T-1302E/TT | 1.3 V fixed, 6 µA IQ, but only 250 mA max output and 600 mV dropout at 250 mA; no PSRR spec >10 kHz. | Higher dropout and uncharacterized high-frequency PSRR limit use in RF-sensitive designs. | Choose for cost-sensitive, non-RF applications with ample input headroom and relaxed noise requirements. |
Compared with TPS71713DCKR, TPS7A0513PDBVR offers lower quiescent current but sacrifices PSRR above 10 kHz and noise filtering; MCP1700T-1302E/TT provides higher output current but lacks verified high-frequency rejection and NR functionality essential for RF/analog coexistence.

FAQ
What is the minimum input voltage required for TPS71713DCKR to regulate 1.3 V output?
The TPS71713DCKR requires a minimum input voltage of 2.5 V per datasheet specifications, which exceeds the theoretical dropout requirement (1.3 V + 0.17 V = 1.47 V) due to internal UVLO and bias circuitry constraints. Below 2.5 V, the device remains disabled even if headroom is sufficient.
Can TPS71713DCKR operate without the noise reduction (NR) capacitor?
Yes, TPS71713DCKR functions without the NR capacitor, delivering 30 µVRMS output noise. However, adding a 0.01 µF ceramic capacitor to the NR pin reduces noise to 16.3 µVRMS, making it essential for applications like high-resolution ADC references where sub-20 µVRMS noise is mandatory.
What is the maximum junction temperature and thermal shutdown behavior of TPS71713DCKR?
The TPS71713DCKR triggers thermal shutdown at approximately 160°C junction temperature and resets at ~140°C. This hysteresis prevents oscillation during overload. Continuous thermal cycling degrades reliability, so design must limit steady-state TJ to ≤125°C using appropriate PCB copper area or thermal vias.
Is TPS71713DCKR stable with ceramic output capacitors smaller than 1 µF?
No - the TPS71713DCKR is specified and characterized for stability only with ≥1 µF ceramic output capacitance. Using smaller values risks oscillation or degraded transient response, as confirmed in Section 6.3 of the datasheet and layout guidelines.
Does TPS71713DCKR support reverse current protection?
No, the TPS71713DCKR does not integrate reverse current protection. Its PMOS pass transistor includes a body diode that conducts when VOUT > VIN. If reverse current flow is possible in the system, an external Schottky diode or ideal diode controller must be added to prevent backfeeding.
