ADP150AUJZ-2.5-R7: High-Performance CMOS Linear Regulator

The ADP150AUJZ-2.5-R7 from Analog Devices Inc. is a highly efficient, low quiescent current linear regulator that operates from 2.2 V to 5.5 V and provides up to 150 mA of output current. This makes it an ideal choice for battery-operated devices and other applications where power efficiency is paramount. The fixed output voltage of 2.5V ensures a stable voltage supply for sensitive electronic components.

Designed with advanced CMOS technology, the ADP150 offers excellent transient response and very low dropout voltage, which is typically just 145 mV at 150 mA load. This characteristic allows for continuous operation as the input voltage approaches the output voltage, extending battery life in portable applications.

The ADP150AUJZ-2.5-R7 comes in a compact TSOT-5 package, making it suitable for space-constrained applications. Its small footprint does not compromise its performance, as it includes features such as low noise, high accuracy, and a low shutdown current of less than 1 µA, which further enhances its power-saving capabilities.

Key features of the ADP150AUJZ-2.5-R7 include:

• Fixed output voltage: 2.5V
• Maximum output current: 150 mA
• Low dropout voltage: 145 mV at 150 mA load
• Wide input voltage range: 2.2 V to 5.5 V
• Low quiescent current: 11 µA (typical)
• High PSRR: 70 dB at 1 kHz
• No-load shutdown current: < 1 µA
• Over-temperature and over-current protection

With its high power supply rejection ratio (PSRR) of 70 dB at 1 kHz, the ADP150 is capable of suppressing power supply noise and fluctuations, ensuring a clean and stable output voltage. This is particularly important for RF and precision analog applications where noise can severely impact performance.

The device also incorporates several safety features, including over-temperature and over-current protection, to safeguard against conditions that could potentially damage the regulator or the device it powers.

In summary, the ADP150AUJZ-2.5-R7 from Analog Devices Inc. is a reliable and efficient solution for applications requiring a stable and noise-free power supply. Its combination of low dropout performance, high PSRR, and safety features make it a versatile choice for designers looking to enhance the performance and longevity of their products.
