概要

Description

The ADP151AUJZ-3.3 is a low-dropout (LDO) voltage regulator from Analog Devices, designed to provide a stable output voltage of 3.3V. It features a high power supply rejection ratio (PSRR), which minimizes voltage variations from the input. The device can deliver up to 150 mA of output current, making it suitable for a variety of applications, including portable devices, RF applications, and battery-powered systems.
Key features include a low dropout voltage, typically around 200 mV at full load, ensuring efficient operation even with minimal input voltage headroom. The ADP151AUJZ-3.3 also offers excellent transient response and a range of protection mechanisms, including thermal overload and short-circuit protection.
Additionally, the LDO operates over a wide temperature range and is packaged in a compact 5-lead TSOT package, facilitating easy integration into space-constrained designs. Overall, the ADP151AUJZ-3.3 is an efficient, reliable choice for applications requiring a stable 3.3V power supply.

Features

The ADP151AUJZ-3.3 is a low-dropout (LDO) voltage regulator that provides a stable output voltage of 3.3V. Key features include:
1. Input Voltage Range: Operates from 2.7V to 5.5V, suitable for a variety of power supply applications.
2. Output Current: Capable of delivering up to 150 mA of output current, making it suitable for powering small loads.

4. Low Quiescent Current: Approximately 25 µA in no load conditions, enhancing battery life in portable applications.
5. Power Supply Rejection Ratio (PSRR): High PSRR ensures minimal output voltage variation from input noise.
6. Thermal Shutdown: Integrated protection mechanism to prevent damage from excessive temperatures.
7. Small Package: Available in a compact 5-lead SOT-23 package, facilitating space-saving designs.
These features make the ADP151AUJZ-3.3 ideal for portable devices and low-power applications.

Package

The ADP151AUJZ-3.3 is packaged in a SOT-23-5 type package. This compact surface-mount package is designed for low-power applications, providing a small footprint suitable for space-constrained environments.

Pinout

The ADP151AUJZ-3.3 is a low-dropout (LDO) voltage regulator with a pin count of 5.
Pin functions are as follows:
1. Input (VIN): This pin connects to the input voltage supply.
2. Ground (GND): This pin is the ground reference for the device.
3. Output (VOUT): This pin provides the regulated output voltage (3.3V).
4. Enable (EN): This pin is used to enable or disable the output. A high signal enables the regulator, while a low signal disables it.
5. Adjust (ADJ): This pin is used for setting the output voltage; however, in the ADP151AUJZ-3.3 variant, it is typically internally connected for fixed output.
The ADP151AUJZ-3.3 is suitable for applications requiring a stable 3.3V supply with low dropout voltage and low quiescent current.
