Product details
Overview
TPS71727DCKTG4 from Texas Instruments is a fixed-output, 2.7 V, 150-mA low-dropout linear regulator in SC-70-5 package, featuring ultra-high PSRR (70 dB at 1 kHz), 30 µVRMS output noise (100 Hz–100 kHz), and 170 mV typical dropout at full load - deployed in camera sensor power rails where low noise and fast transient response are critical.
For engineers reviewing the TPS71727DCKTG4 datasheet, TPS71727DCKTG4 pinout, TPS71727DCKTG4 application, or TPS71727DCKTG4 equivalent, key selection considerations include its 2.5 V to 6.5 V input range, 3% output accuracy over temperature/load, enable-controlled standby mode, and stability with only 1 µF ceramic output capacitance.
Technical Context
The TPS71727DCKTG4 uses a PMOS pass device and high-gain BiCMOS error amplifier to achieve fast startup (≤160 µs with 0.01 µF NR capacitor), excellent line/load transient response, and high PSRR across 100 Hz–1 MHz despite sub-200 mV dropout. Its noise reduction (NR) pin filters bandgap reference noise, enabling 30 µVRMS output noise when paired with a 0.01 µF capacitor.
It integrates undervoltage lockout (UVLO rising at 2.45 V), thermal shutdown (160°C trip), and current limiting (≥200 mA). The SC-70-5 package supports compact layouts in space-constrained portable systems without requiring external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7 V ±3% over –40°C to 125°C, load, and line variation - ensures stable bias for image sensors and RF front-ends. |
| Max Output Current | 150 mA continuous - sufficient for CMOS image sensor analog/IO domains and low-power Bluetooth transceivers. |
| Dropout Voltage | 170 mV typical at 150 mA - enables operation from 2.87 V input, supporting single-cell Li-ion or regulated 3.3 V rail derating. |
| PSRR | 70 dB at 1 kHz, 67 dB at 100 kHz, 45 dB at 1 MHz - suppresses switching noise from DC/DC converters feeding adjacent circuits. |
| Output Noise | 30 µVRMS (100 Hz–100 kHz) with 0.01 µF NR capacitor - meets stringent noise requirements of high-resolution ADCs and RF synthesizers. |
| Ground Current | 45 µA typical at light load, 100 µA at 150 mA - extends battery life in always-on mobile camera modules. |
| Enable Threshold | VEN(HIGH) = 1.2 V min - compatible with 1.8 V GPIO and low-voltage microcontrollers without level shifting. |
Pinout & Package
TPS71727DCKTG4 is packaged in a 5-pin SC-70 (DCK) package, 2.00 mm × 1.25 mm, with exposed pad not present. Pinout is validated per TI SBVS068I Rev I datasheet Figure 5 (DCK Top View).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input supply connection | Accepts 2.5–6.5 V; requires ≥0.1 µF ceramic bypass capacitor close to pin for stability and EMI suppression. |
| 2 - GND | Power ground reference | Low-impedance return path for regulator core and feedback loop; must be connected directly to PCB ground plane. |
| 3 - EN | Active-high enable control | Pulling ≥1.2 V enables regulation; ≤0.4 V disables output and reduces ground current to ≤1.5 µA. |
| 4 - NR | Noise reduction filter node | Connects to 0.01 µF ceramic capacitor to reduce bandgap reference noise and improve PSRR below 100 kHz. |
| 5 - OUT | Regulated output voltage | Delivers 2.7 V ±3%; requires ≥1 µF ceramic output capacitor (X5R/X7R) for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise with NR pin | 30 µVRMS output noise achieved via dedicated NR pin filtering bandgap reference - eliminates need for post-regulation LC filters in noise-sensitive signal chains. |
| High PSRR up to 1 MHz | 70 dB @ 1 kHz and 45 dB @ 1 MHz - maintains clean 2.7 V supply even when co-located with noisy buck converters operating at 1–2 MHz. |
| Fast startup with quick-start circuit | ≤160 µs turn-on time with 0.01 µF NR capacitor - enables rapid power sequencing in camera auto-focus or burst capture modes. |
| Stable with minimal output capacitance | Guaranteed stability with only 1 µF ceramic output capacitor - reduces BOM count and PCB area vs. traditional LDOs requiring ≥10 µF. |
| Thermal and current protection | Integrated thermal shutdown (160°C trip) and current limit (≥200 mA) - prevents damage during short-circuit or overload without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS71727DCKR | Same electrical specs and SC-70-5 package; G4 suffix indicates green (RoHS-compliant) and lead-free finish, while R suffix denotes standard tape-and-reel packaging without enhanced environmental compliance. | No functional difference in circuit operation; DCKR lacks TI's enhanced moisture sensitivity and halogen-free labeling required for some automotive or industrial certifications. | Select TPS71727DCKTG4 when RoHS-6, lead-free, and J-STD-020-compliant assembly is mandated; otherwise DCKR offers identical performance at lower cost. |
| MCP1700T-2702E/TT | 2.7 V fixed output, 250 mA rating, but higher 115 µVRMS noise and only 55 dB PSRR at 1 kHz; SOT-23-3 package lacks enable and NR pins. | Suitable for non-noise-critical digital rails but cannot replace TPS71727DCKTG4 in RF or high-resolution imaging applications due to inferior PSRR and noise. | Choose MCP1700T-2702E/TT only for cost-sensitive, low-performance applications where 30 µVRMS noise and 70 dB PSRR are not required. |
Compared with TPS71727DCKR, the TPS71727DCKTG4 adds RoHS-6 and lead-free compliance without performance trade-offs; versus MCP1700T-2702E/TT, it delivers 40% lower noise and 15 dB higher PSRR - critical for RF and imaging systems where supply integrity directly impacts signal fidelity.

FAQ
What is the maximum input voltage rating for the TPS71727DCKTG4?
The TPS71727DCKTG4 has an absolute maximum input voltage of 7 V, but its recommended operating input range is 2.5 V to 6.5 V. Exceeding 6.5 V may trigger internal protection or degrade reliability. For 2.7 V output, minimum valid input is 2.87 V (2.7 V + 170 mV typical dropout), and operation below 2.5 V is prohibited per datasheet Section 6.3.
Does the TPS71727DCKTG4 require an external noise reduction capacitor?
Yes - the TPS71727DCKTG4's NR pin must be connected to a 0.01 µF ceramic capacitor (X5R/X7R) to achieve its specified 30 µVRMS output noise. Omitting the NR capacitor increases noise to ~95 × VOUT µVRMS (≈257 µVRMS). The quick-start circuit fully charges this capacitor within 135 µs at power-on.
Can the TPS71727DCKTG4 be used without an enable signal?
Yes - the TPS71727DCKTG4 can operate continuously by connecting the EN pin directly to IN. This configures it as a simple drop-in LDO with no external control. However, doing so forfeits the <1.5 µA shutdown current benefit and removes power sequencing capability essential in battery-powered camera modules.
What output capacitor value is required for stability with the TPS71727DCKTG4?
The TPS71727DCKTG4 is stable with a minimum 1 µF ceramic output capacitor (X5R or X7R dielectric). Larger values (up to 100 µF) improve transient response but are not required. Avoid tantalum or aluminum electrolytic capacitors due to ESR-related instability risks confirmed in TI SBVS068I Section 8.1.
Is the TPS71727DCKTG4 pin-compatible with other TPS717xx variants in SC-70-5 package?
Yes - all TPS717xx devices in the DCK (SC-70-5) package share identical pinout, footprint, and thermal characteristics. The TPS71727DCKTG4 is functionally interchangeable with TPS71712DCKTG4, TPS71718DCKTG4, etc., provided the output voltage matches system requirements and the NR pin is properly configured for each fixed-voltage variant.
