Overview

The AP2210N-3.0TRG1 is a 300mA positive fixed LDO voltage regulator designed for low-noise and high-precision applications. It features a high PSRR of 75dB at 100Hz and a low dropout voltage of 0.5V at full load, making it suitable for sensitive RF and analog circuits. The device includes integrated protection features such as thermal shutdown, over-current limiting, and reverse current protection.

Why Choose This Part

This regulator offers high output accuracy of 1 percent and a low noise floor of 260 nV/sqrt(Hz). Its SOT-23-3 package provides a small footprint for space-constrained designs while incorporating robust logic-controlled enable and reverse current protection.

Applications

RF and Wireless Communication
Provides clean, low-noise power for wireless communicators and cellular handsets where signal integrity is critical.
Battery-Powered Handhelds
Utilizes a low standby current of 5uA to extend battery life in PDAs and portable consumer electronics.
Analog Signal Conditioning
High 75dB PSRR helps filter power supply ripple in precision analog stages and sensor interfaces.
Microcontroller Peripheral Power
Supplies stable 3.0V power to digital logic and sensors on PC motherboards and embedded systems.

Getting Started

To implement the AP2210N-3.0TRG1, ensure an input voltage between 4V and 13.2V is provided. Follow the datasheet recommendations for output capacitor ESR to maintain stability under the 300mA maximum load. The SOT-23-3 footprint requires standard SMD soldering techniques and thermal management through PCB copper pour for the GND pin.
