The TPRT9161-50GV with SOT-23-3L Linear Voltage Regulators, also known as an LDO, is a voltage regulator designed and manufactured by TECH PUBLIC. It is RoHS compliant and is designed to regulate a specific input voltage into a regulated output voltage, typically 5 V, while also providing a regulated current flow. This device is an easy to use, low-dropout voltage regulator with a high PSRR, enabling it to provide clean power even in noisy environments. It offers good line and load regulation, and is suitable for battery-powered applications that require low dropout and low power consumption. It has an operating temperature range of -40°C to +85°C, and is suitable for use with a range of input voltages from 4.3 V to 5.5 V. This device is ideal for use in applications such as power buffers, LCD bias supplies, and audio supplies.
