Linear Voltage Regulators are essential components in power management systems, many of which are electronic circuits used to maintain a steady voltage output between an input and output, regardless of fluctuations in either the output current or load. The STMicroelectronics LE50CZ-TR is an example of such a device, and this article will explore its application field and working principle.

Applications of the LE50CZ-TR are varied, but the device is most often used to provide power supply voltage conditioning, such as filtering, in consumer and automotive electronics. This small form-factor voltage regulator can provide a fixed output voltage in the range of 0.8 V to 5 V, making it ideal for circuit designs requiring precise, low noise outputs at high efficiency. Additionally, its wide input voltage range (1.8 V to 17 V) makes it suitable for a wide range of automotive applications, most commonly used in under-the-hood systems such as engine controls and dashboard modules.

In terms of its working principle, the LE50CZ-TR is essentially a switching regulator with a built-in low dropout regulator (LDO). An LDO is a type of voltage regulator which maintains a fixed output voltage regardless of variations in the load current drawn from it. This is achieved by using an internal feedback loop to monitor changes in the output voltage and adjust the current supplied to the circuit accordingly. In the case of the LE50CZ-TR, the LDO section of the regulator is supplemented by an advanced high frequency synchronous rectification technique to reduce power consumption. The result is an efficient, low noise regulator with a high power supply rejection ratio (PSRR).

The LE50CZ-TR also features advanced circuitry designed to protect against short-circuits and over-current. This is achieved via a special current limitation circuit which engages at an adjustable current threshold, thereby limiting the amount of current supplied to the circuit and protection it from any damage. This feature makes the LE50CZ-TR an ideal choice for automotive applications, as it is able to prevent damage to components in the event of a short circuit or overload.

STMicroelectronics’ LE50CZ-TR is a versatile Linear Voltage Regulator suited for a wide range of low power applications. Its low power consumption, high efficiency and high PSRR make it an ideal choice for automotive electronics where reliability and performance are paramount. Additionally, its advanced circuitry makes it resistant to short-circuits, a useful feature for high-voltage applications. While it is primarily used for voltage conditioning, the LE50CZ-TR can be used to provide a regulated fixed voltage output for a wide range of applications requiring a precise, low noise output.
