Texas Instruments LM9076BMAX-3.3/NOPB

Overview

LM9076BMAX-3.3/NOPB from Texas Instruments is a ±3% accuracy, 150 mA ultra-low quiescent current LDO regulator with integrated delayed reset output and shutdown control, featuring 25 µA typical ground pin current at 100 µA load, 200 mV typical dropout at 150 mA, and operation across −40°C to +125°C for automotive battery-supplied systems.

For engineers reviewing the LM9076BMAX-3.3/NOPB datasheet, LM9076BMAX-3.3/NOPB pinout, LM9076BMAX-3.3/NOPB application, or LM9076BMAX-3.3/NOPB equivalent, this page delivers verified electrical parameters, SOIC-8 package mapping, reset delay timing behavior, shutdown logic thresholds, and validated automotive-grade alternatives - all confirmed against TI's SNVS260L datasheet (Rev. March 2013).

Technical Context

The LM9076BMAX-3.3/NOPB employs a PNP pass transistor architecture enabling low-dropout operation while maintaining stability with ≥10 µF output capacitance and specified ESR range. Its active-low open-collector RESET pin responds to VOUT falling below 0.89×VOUT (typical) after programmable delay set by external CDELAY capacitor.

Shutdown control is implemented via a dedicated SHUTDOWN pin (only on BMA variants), with VIH(SD) = 1.5–2.0 V and VIL(SD) = 1.0–1.5 V thresholds, enabling direct interface with microcontroller GPIOs. Thermal shutdown activates at ~160°C junction temperature, and input transient protection covers +70 V/−50 V pulses.

FAQ

What is the maximum input voltage the LM9076BMAX-3.3/NOPB can withstand continuously?

The LM9076BMAX-3.3/NOPB supports continuous input voltage from 5.35 V to 40 V DC. It also tolerates short-duration transients up to +70 V (≤10 ms, <1% duty cycle) and −50 V (≤1 ms, <1% duty cycle), meeting ISO 7637-2 Pulse 5a requirements for automotive applications. This eliminates need for external TVS diodes in most vehicle power designs.

How is the reset delay time calculated for LM9076BMAX-3.3/NOPB?

The reset delay time for LM9076BMAX-3.3/NOPB is calculated using tDELAY = VOUT × CDELAY / IDELAY, where VOUT = 3.3 V, IDELAY = 0.42 µA (typical), and CDELAY is the external capacitor value. With a 0.001 µF capacitor, tDELAY = 3.3 V × (0.001 µF / 0.42 µA) ≈ 7.8 ms. This delay ensures MCU reset remains asserted until power rails stabilize.

Does LM9076BMAX-3.3/NOPB require an output capacitor, and what are the requirements?

Yes, LM9076BMAX-3.3/NOPB requires a minimum 10 µF output capacitor with ESR between 0.5 Ω and 4.0 Ω for stability. TI recommends ≥22 µF solid tantalum or ceramic capacitors (with series resistor if ESR is too low). Aluminum electrolytics are discouraged due to ESR drift over temperature. The capacitor must be placed close to VOUT and GND pins.

What is the shutdown behavior of LM9076BMAX-3.3/NOPB?

LM9076BMAX-3.3/NOPB enters shutdown when SHUTDOWN pin voltage exceeds 1.5 V (VIH threshold), reducing output to near-zero and limiting ground pin current to ≤10 µA. The regulator resumes operation when SHUTDOWN falls below 1.0–1.5 V (VIL threshold). This enables microcontroller-controlled power gating in low-power modes.

Is LM9076BMAX-3.3/NOPB qualified for automotive use?

Yes, LM9076BMAX-3.3/NOPB is designed and tested for automotive applications: it operates across −40°C to +125°C junction temperature, includes +70 V/−50 V transient protection, and meets AEC-Q100 stress test requirements (ESD HBM ±2 kV, MM ±250 V). Its SOIC-8 package (D) is rated for automotive-grade reflow and long-term reliability.
