Product details
Overview
TPS71715DCKTG4 from Texas Instruments is a fixed-output, 1.5 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 - designed for noise-sensitive analog and RF power rails in portable imaging and wireless systems.
For engineers reviewing the TPS71715DCKTG4 datasheet, TPS71715DCKTG4 pinout, TPS71715DCKTG4 application, or TPS71715DCKTG4 equivalent, key selection criteria include its 45-µA quiescent current, 1-µF ceramic capacitor stability, NR-pin-enabled noise filtering, and operation across –40°C to 125°C junction temperature.
Technical Context
The TPS71715DCKTG4 uses a PMOS pass device with BiCMOS process technology to achieve fast startup, low noise, and high PSRR without requiring external compensation. Its error amplifier features precision voltage reference and feedback loop ensuring ±3% worst-case output accuracy over load, line, temperature, and process variations.
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). The NR pin enables optional 0.01 µF noise reduction capacitor to lower output spectral noise density by up to 9×.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±3% over full operating range - ensures stable bias for low-voltage analog sensors and RF front-ends. |
| Max Output Current | 150 mA continuous - sufficient for camera ISPs, Bluetooth baseband ICs, and low-power MCU cores. |
| Dropout Voltage | 170 mV typical at 150 mA - enables operation from 1.65 V input, supporting single-cell Li-ion or Li-poly battery systems. |
| 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 rails. |
| Output Noise | 30 µVRMS (100 Hz–100 kHz) with CNR = 0.01 µF - meets stringent SNR requirements of CMOS image sensors and ADC references. |
| Quiescent Current | 45 µA typical - extends battery life in always-on sensor nodes and standby-mode mobile peripherals. |
| Operating Temp | –40°C to +125°C junction - qualified for automotive cabin modules and industrial handheld terminals. |
Pinout & Package
TPS71715DCKTG4 is housed in a 5-pin SC-70 (DCK) package measuring 2.00 mm × 1.25 mm, optimized for space-constrained portable PCBs. Thermal performance is characterized by RθJA = 279.2°C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Input supply connection | Accepts 2.5 V–6.5 V; requires 0.1–1 µF ceramic decoupling close to pin for stability and transient response. |
| 2 GND | Power ground reference | Low-impedance return path for regulator core and output stage; must be connected to solid ground plane. |
| 3 EN | Enable control input | Active-high TTL/CMOS-compatible; drives >1.2 V to enable, <0.4 V to enter 0.2–1.5 µA shutdown mode. |
| 4 NR | Noise reduction filter node | Connects to 0.01 µF ceramic capacitor to reduce bandgap reference noise and improve PSRR above 10 kHz. |
| 5 OUT | Regulated output | Delivers 1.5 V ±3%; requires ≥1 µF ceramic output capacitor (X5R/X7R) for loop stability and load transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise regulation | 30 µVRMS output noise with NR capacitor - enables clean power for high-resolution image sensors and precision ADCs. |
| High-bandwidth PSRR | 70 dB at 1 kHz and 67 dB at 100 kHz - rejects ripple from switching regulators without additional LC filtering. |
| Fast startup with NR support | 160 µs typical startup time with 0.01 µF CNR - balances low-noise performance and system boot speed. |
| Zero-load stability | Stable down to 0 mA output current - eliminates need for minimum load resistors in intermittent-sensing applications. |
| Robust protection suite | Integrated UVLO, thermal shutdown (160°C), and current limit - prevents damage during input brownout or overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS71715DCKR | Same silicon, tape-and-reel packaging (no G4 suffix); identical electrical specs and SC-70-5 footprint. | No functional difference; used in high-volume automated assembly where reel packaging is required. | Select TPS71715DCKR for production lines using pick-and-place feeders; TPS71715DCKTG4 is tube-packaged for prototyping and low-volume builds. |
| MCP1700T-1502E/TT | 150 mA, 1.5 V fixed LDO in SOT-23-5; 6 µVRMS noise but only 40 dB PSRR at 1 kHz and 220 mV dropout at 150 mA. | Suitable for cost-sensitive, non-RF applications where ultra-low noise is secondary to price and availability. | Choose MCP1700T-1502E/TT only when PSRR >65 dB and dropout <180 mV are not required; verify thermal derating at 125°C ambient. |
Compared with TPS71715DCKTG4, TPS71715DCKR offers identical performance in reel format for volume manufacturing, while MCP1700T-1502E/TT trades PSRR and dropout for lower cost and wider distributor stock - making it viable only in non-noise-critical digital loads.

FAQ
What is the maximum input voltage rating for the TPS71715DCKTG4?
The TPS71715DCKTG4 has an absolute maximum input voltage of 7 V, but its recommended operating range is 2.5 V to 6.5 V. Exceeding 6.5 V may trigger internal protection or degrade reliability; operation above 7 V risks permanent damage per datasheet Section 6.1.
Does the TPS71715DCKTG4 require an external noise reduction capacitor?
The TPS71715DCKTG4 does not require an external noise reduction capacitor to function, but connecting a 0.01 µF ceramic capacitor between the NR pin and GND reduces output noise by up to 9× and improves PSRR above 10 kHz - a recommended practice for camera sensor and RF applications.
Can the TPS71715DCKTG4 operate with zero load current?
Yes, the TPS71715DCKTG4 is explicitly designed to remain stable with no output load. Its low-current mode circuit maintains loop gain at 0 mA, eliminating the need for minimum load resistors - critical for intermittent-sensing applications like motion-triggered cameras.
What is the thermal shutdown behavior of the TPS71715DCKTG4?
The TPS71715DCKTG4 disables output when junction temperature reaches ~160°C and re-enables at ~140°C. This hysteresis prevents rapid cycling; however, sustained thermal shutdown indicates inadequate heatsinking or excessive power dissipation - design should limit TJ to ≤125°C under worst-case conditions.
Is the TPS71715DCKTG4 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. This allows drop-in replacement across output voltages (0.9 V–5 V) and adjustable versions when layout accommodates NR/FB routing.
