TPS76912QDBVRG4Q1

TPS76912QDBVRG4Q1 Description

The TPS76912QDBVRG4Q1 is a fixed-output, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for automotive-grade applications. This 100mA regulator delivers a stable 1.2V output from an input voltage range up to 10V, making it suitable for low-power, precision voltage regulation in harsh environments. With a quiescent current of just 28 µA, it optimizes power efficiency, while its 60dB PSRR (1kHz) ensures excellent noise rejection. The device is housed in a compact SOT23-5 package, ideal for space-constrained designs.
