Texas Instruments TPS71713DCKT

Overview

TPS71713DCKT from Texas Instruments is a fixed-output, 1.3-V, 150-mA low-dropout linear regulator in a 5-pin SC-70 package. It delivers ultra-low noise (30 µV_RMS, 100 Hz–100 kHz), high PSRR (70 dB at 1 kHz), and low dropout (170 mV typical at 150 mA) for precision analog and RF power rails in space-constrained portable systems.

For engineers reviewing the TPS71713DCKT datasheet, TPS71713DCKT pinout, TPS71713DCKT application, or TPS71713DCKT equivalent, key selection criteria include output accuracy (±3% over load/line/temp), enable-controlled shutdown (I_SHDN = 0.2–1.5 µA), thermal protection (160°C trip), and stability with only 1-µF ceramic output capacitance.

Technical Context

The TPS71713DCKT uses a PMOS pass device and advanced BiCMOS process to achieve fast startup, excellent transient response, and high PSRR across wide frequency range - 70 dB at 1 kHz, 67 dB at 100 kHz, and 45 dB at 1 MHz - while maintaining 45-µA ground current in active mode. Its noise reduction (NR) pin accepts a 0.01-µF capacitor to filter bandgap reference noise, lowering output noise to 30 µV_RMS.

It integrates undervoltage lockout (UVLO rising threshold 2.45 V), thermal shutdown (160°C trip / 140°C reset), and current limiting (200–575 mA). The SC-70-5 package enables compact layout with minimal board area, and the device operates across –40°C to +125°C junction temperature.

FAQ

What is the maximum input voltage rating for the TPS71713DCKT?

The TPS71713DCKT has an absolute maximum input voltage (VIN) of 7 V. However, its recommended operating range is 2.5 V to 6.5 V. Exceeding 7 V risks permanent damage, and operation above 6.5 V violates recommended conditions and may degrade PSRR or noise performance. Always maintain VIN within 2.5–6.5 V for reliable TPS71713DCKT operation.

Does the TPS71713DCKT require an external noise reduction capacitor?

Yes - the TPS71713DCKT's NR pin must be connected to a 0.01 µF ceramic capacitor (X5R/X7R) to achieve its specified 30 µV_RMS output noise. Without this capacitor, output noise rises significantly (e.g., 95 × VOUT ≈ 124 µV_RMS). The quick-start circuit fully charges this capacitor in ~135 µs, ensuring fast, low-noise startup for the TPS71713DCKT.

Can the TPS71713DCKT operate without any output load?

Yes - the TPS71713DCKT is explicitly designed to remain stable with zero output load. Its low-current mode circuit maintains loop gain under no-load conditions, eliminating the need for a minimum load resistor. This feature is essential for battery-powered devices that frequently enter deep-sleep states, ensuring consistent regulation and avoiding unnecessary power loss in the TPS71713DCKT.

What is the enable pin behavior when left unconnected on the TPS71713DCKT?

When the EN pin of the TPS71713DCKT is left floating, it is internally pulled down, placing the device in shutdown mode (I_SHDN ≤1.5 µA). To activate regulation, EN must be driven to ≥1.2 V. For always-on operation, tie EN directly to VIN. Do not leave EN unconnected in production designs unless intentional shutdown is required - unintended floating can cause erratic TPS71713DCKT behavior.

How does thermal shutdown function in the TPS71713DCKT?

The TPS71713DCKT activates thermal shutdown at approximately 160°C junction temperature, disabling the output until the die cools to ~140°C. This 20°C hysteresis prevents oscillation near the trip point. Cycling indicates excessive power dissipation - for reliable TPS71713DCKT operation, keep TJ ≤125°C using adequate PCB copper area or thermal vias, especially at 150 mA load in the SC-70 package.
