TPS7B4250QDBVRQ1 TI Voltage Regulators - Linear, Low Drop Out (LDO)
The TPS7B4250-Q1 is an automotive-grade, 50-mA low-dropout linear regulator with a fixed 5.0V output, qualified for AEC-Q100. It operates from a 4V to 40V input and features an ultra-low quiescent current of 4.5µA typical, making it suitable for battery-connected, always-on automotive applications. The device includes thermal shutdown, current limiting, and reverse current protection. Packaged in a 5-pin SOT-23 (DBV) (2.9mm × 1.6mm), it is ideal for body control modules (BCMs), infotainment systems, and ADAS sensors requiring a clean, low-power 5V rail. Applications include CAN/transceiver power, sensor supplies, and microcontroller bias. In stock at HL Electronics – request a quote for fast delivery.
