TPS79918QDDCRQ1 200 mA LDO regulator
The TPS79918QDDCRQ1 is an AEC-Q100-qualified, 200 mA, ultra-low-noise LDO from Texas Instruments that delivers a fixed 1.8 V output in a SOT-23-THIN package, merging automotive-grade robustness with consumer-class performance for space-constrained, noise-sensitive rails in camera, radar and infotainment domains. Built on an advanced BiCMOS process, the regulator consumes only 40 µA ground current, achieves 100 mV typical dropout at 200 mA, and integrates an enable pin and soft-start-controlled current limit that clamps in-rush to protect downstream SoCs and ADCs during hot-plug events. Operating from 2.7 V to 6.5 V input, it maintains ±1 % DC accuracy across –40 °C to +125 °C, survives 6.5 V transient and reverse-battery conditions, and is fully stable with a single 2.2 µF ceramic capacitor, shrinking BOM to one chip and one cap while meeting stringent CISPR-25 EMC limits in automotive camera modules and sensor hubs.
