The L4947PD013TR is a linear voltage regulator with a wide range of applications. It provides a high accuracy output of up to ±1% over line, load, and temperature conditions. Due to its low operating current, low quiescent current, and low temperature coefficient, it is well suited for applications that require high accuracy and high power efficiency.

The L4947PD013TR is a three-terminal adjustable voltage regulator with a current source-like output stage. It is designed to regulate the output voltage from 0.8 V to 5 V with a minimum output current of 5 mA. It accepts an input voltage from 8 V to 35 V and draws a maximum quiescent current of 5 µA. The output voltage is maintained at a constant level by an internal error amplifier, which operates at a gain of 50 dB.

The L4947PD013TR has a fixed or adjustable output voltage and is capable of providing current regulation over a wide range at low voltages. In addition, it features over-current, over-temperature and over-voltage protection, allowing it to be used in high power applications without compromising system reliability. The L4947PD013TR is also well suited for battery-powered applications and can be used in portable equipment, automotive systems, and low voltage consumer electronics.

The L4947PD013TR is designed with an integrated short-circuit protection circuit. A short circuit from the output of the regulator to ground triggers the SC protects circuit that shuts down the regulator and limits the current to the output terminal. The design prevents the device from overheating, providing an additional level of system reliability.

The L4947PD013TR has an internal thermal shut-down (TSD) circuit that acts as a safeguard for the internal components. The circuit monitors the junction temperature of the device and shuts down the regulator if the temperature exceeds a predetermined limit. This feature will help to protect the regulator from being damaged due to high temperature conditions.

The L4947PD013TR is a very versatile and reliable device, suitable for a variety of applications. It is widely used in automotive, consumer electronics, and industrial applications. Its accurate voltage and current regulation, coupled with the comprehensive protection features, make it an ideal choice for these applications.
