The TLV1171 is a 1-A positive fixed voltage low-dropout (LDO) regulator designed by Texas Instruments. It operates with an input voltage range of 2.0 V to 5.5 V and features a low quiescent current of 100 ¬µA, significantly lower than traditional 1117 devices. The regulator has a dropout voltage of 455 mV at 1 A for a 3.3 V output, making it suitable for applications requiring efficient power management. This device is stable with no minimum load current requirement, allowing it to function effectively even at low output currents. It provides a high power-supply rejection ratio (PSRR) of 65 dB at 1 kHz, which is beneficial for reducing noise in sensitive applications. The TLV1171 also includes thermal shutdown and overcurrent protection features, enhancing its reliability in various operating conditions. The operating temperature range for the TLV1171 is from -40¬8C to +125¬8C, and it is available in a compact SOT-223 package, making it suitable for space-constrained designs. This regulator is ideal for applications such as set-top boxes, PC peripherals, and communication devices, where low power consumption and stability are critical.
