Mingjiada Electronics offers the TI TPS7B8401QWDRBRQ1, a low-dropout (LDO) linear regulator specifically designed for automotive applications, featuring outstanding performance and high reliability.
Product Overview
The TI TPS7B8401QWDRBRQ1 is an automotive-grade low-dropout linear regulator (LDO). This device is housed in an 8-VDFN (3×3mm) package, specifically designed for harsh automotive electronic environments. It supports a wide input voltage range from 3V to 40V and can withstand transient voltages up to 42V, making it suitable for critical applications such as vehicle battery power supply systems, CAN transceivers, and microcontroller (MCU) backup power supplies.
The TPS7B8401QWDRBRQ1, with its ultra-low static current of 18µA and ±0.75% output voltage accuracy, is an ideal choice for automotive electronic power management. Mingjiada Electronics ensures that every TPS7B8401QWDRBRQ1 supplied is an authentic TI original product and provides comprehensive technical support and fast delivery services.
Core Features and Parameters
1. Automotive-grade high reliability
AEC-Q100 certified, operating temperature range -40°C to +150°C (junction temperature), suitable for extreme automotive environments.
40V wide input voltage, supporting automotive cold start (as low as 3V) and load dump (42V transient).
Low static current: only 18µA (typical), reduced to 4µA when disabled, optimising energy efficiency for always-on systems.
2. High-performance power management
Output voltage range: 1.2V to 18V (adjustable) or fixed 3.3V/5V, meeting diverse load requirements.
Low voltage drop: 225mV @150mA (VOUT ≥ 3.3V), reducing power loss.
Fast transient response: ±2% VOUT deviation during cold start, ensuring system stability.
High PSRR: 55dB @1kHz, effectively suppressing power supply noise.
3. Integrated Protection Features
Overcurrent protection (OCP), over-temperature protection (TSD), and under-voltage lockout (UVLO) enhance system robustness.
Wettable flank packaging facilitates PCB automatic optical inspection (AOI).
Applications
• Reconfigurable instrument clusters
• Body control module (BCM)
• Normally open battery connection applications:
– Automotive gateway
– Remote keyless entry (RKE)
