Texas Instruments TPS76150DBVRG4

Overview

TPS76150DBVRG4 from Texas Instruments is a 100-mA low-dropout linear regulator with fixed 5-V output, 170-mV typical dropout at full load, <1 µA shutdown quiescent current, and operation across –40°C to 125°C junction temperature-designed for space-constrained battery-powered systems such as portable instrumentation and low-power microcontroller power rails.

For engineers reviewing the TPS76150DBVRG4 datasheet, TPS76150DBVRG4 pinout, TPS76150DBVRG4 application, or TPS76150DBVRG4 equivalent, key selection criteria include dropout voltage under 100-mA load, thermal protection behavior, EN logic thresholds, output capacitor ESR requirements (0.1–10 Ω), and SOT-23 (DBV) package compatibility with high-density PCB layouts.

Technical Context

The TPS76150DBVRG4 employs a BiCMOS process to achieve ultra-low quiescent current and stable regulation under light-to-full load conditions. Its internal architecture integrates current limiting, thermal shutdown (trip at 160°C, recovery at 150°C), and enable-controlled sleep mode with sub-1-µA standby draw.

It requires a minimum 4.7-µF output capacitor with ESR between 0.1 Ω and 10 Ω for loop stability and delivers 63 dB ripple rejection at 1 kHz. Input voltage range is 5.38 V to 16 V, with reverse current path inherent in the pass transistor structure.

FAQ

What is the maximum input voltage for the TPS76150DBVRG4?

The TPS76150DBVRG4 supports an absolute maximum input voltage of 16 V. Its recommended operating input range is 5.38 V to 16 V, ensuring proper regulation while maintaining safe margin against dropout and thermal stress. Exceeding 16 V risks permanent damage per absolute maximum ratings.

Does the TPS76150DBVRG4 require an external output capacitor, and what are its specifications?

Yes, the TPS76150DBVRG4 requires a minimum 4.7-µF output capacitor with ESR between 0.1 Ω and 10 Ω for loop stability. Solid tantalum, aluminum electrolytic, or multilayer ceramic capacitors meeting these values are acceptable. Using a capacitor outside this ESR range may cause oscillation or poor transient response.

How does the enable (EN) pin function on the TPS76150DBVRG4?

The EN pin on the TPS76150DBVRG4 is active-high: applying ≥2 V enables regulation, while ≤0.8 V places the device in shutdown mode with <1 µA quiescent current. The pin draws only 2.5–5 µA when high and –1 to 1 µA when low. It must never be left floating-tie to IN if unused.

What thermal protection behavior does the TPS76150DBVRG4 exhibit?

The TPS76150DBVRG4 features thermal shutdown that activates at approximately 160°C junction temperature and recovers automatically when the die cools to ~150°C. This hysteresis prevents cycling during sustained overload. The device also includes current limiting to reduce power dissipation before thermal trip occurs.

Is the TPS76150DBVRG4 pin-compatible with other TPS761xx variants?

Yes, all TPS761xx devices-including TPS76130DBVRG4, TPS76133DBVRG4, and TPS76150DBVRG4-share identical SOT-23 (DBV) 5-pin pinout and footprint. Only the output voltage differs (3.0 V, 3.3 V, 5.0 V); no PCB redesign is needed when swapping within the family for voltage scaling.
