EL5825IRZ-T13 is an integrated special purpose voltage regulator from Texas Instruments. It is designed to provide adjustable linear voltage regulation in space-constrained architectures. It is ideal for use in memory applications with tight power budgets. The EL5825IRZ-T13 is a member of the TI Simple Switcher family of products, offering simple, easy-to-use, and energy efficient solutions for a wide range of space-constrained applications.

The EL5825IRZ-T13 offers an adjustable linear output voltage range from 1.2 to 3.3V with output current in excess of 800mA. It combines a precision 1.2V reference and an adjustable current-limit MOSFET in a single package, allowing for a fully adjustable output voltage with no external components. This integrated package eliminates the need for external opamps and current-limit resistors, saving both board space and power.

The device offers excellent line and load transient performance, as well as low-noise operation. It features a fast start-up time, allowing for quick and efficient power up. It also offers over voltage protection and a power good signal which can be used to indicate when a stable output voltage is ready. The device is protected against reversed voltages and over current conditions, allowing for use in automated assembly processes. The EL5825IRZ-T13 is available in a compact 16-pin TSSOP package.

The EL5825IRZ-T13 is ideal for applications requiring a reliable, linear, adjustable output voltage source. It is well suited for a wide range of space-constrained applications including memory subsystems and system power. The device can be used to provide a stable output voltage in applications such as LED driving, portable devices, and battery charging systems. The device\'s integrated current-limit MOSFET eliminates the need for external current-limit resistors, saving both board space and power.

The EL5825IRZ-T13 utilizes a PMOS pass transistor to regulate the output voltage. The output voltage is set externally by means of an external voltage divider. This divider sets the threshold voltage of the internal comparator that controls the transistor\'s gate. When the output voltage drops below the threshold voltage, the comparator pulses the gate, allowing the pass transistor to conduct. This raises the output voltage, until the input voltage reaches the preset threshold voltage, at which point the comparator stops pulsing and the pass transistor switches off.

The device also includes a current limit circuit. When the output voltage exceeds the preset threshold voltage, the current limit circuit engages, reducing the current drawn by the pass transistor. This helps maintain a constant output voltage and ensures that the device does not exceed its maximum output current rating. The device is also protected against reversed voltage and over-current conditions, ensuring controlled operation of the power supply.

The EL5825IRZ-T13 is a highly integrated voltage regulator, offering simple, easy-to-use, and energy efficient solutions for a wide range of space-constrained applications. To save board space and power, the device\'s integrated current-limit MOSFET eliminates the need for external current-limit resistors, allowing for a fully adjustable output voltage with no external components. This makes it ideal for memory applications with tight power budgets such as LED driving, portable devices, and battery charging systems. The device offers excellent line and load transient performance, as well as low-noise operation, and is protected against reversed voltages and over-current conditions.
