AAT3215IGV-3.1-T1

Overview

The AAT3215IGV-3.1-T1 is a fixed positive low dropout (LDO) linear regulator manufactured by Skyworks Solutions Inc., formerly Advanced Analog Technology, Inc. It provides a fixed 3.1 V output with a maximum current capability of 150 mA. The device features a typical quiescent current of 95 µA and a low dropout voltage of less than 140 mV at full load. It operates within an input voltage range supporting up to 5.5 V and functions across a temperature range of -40°C to +85°C. The component is housed in a space-saving 5-pin SOT-23 package.

Feature Summary

Designed for very low output noise performance and fast transient response
Features high power supply ripple rejection ratio (PSRR)
Includes low-power shutdown mode for extended battery life
Provides output short-circuit protection and thermal shutdown circuitry

Applications

Powering sensitive RF circuits
Portable electronic devices requiring low noise
Battery-operated handheld electronics

Procurement Notes

Verify the manufacturer status as the original producer was Advanced Analog Technology, Inc., now part of Skyworks Solutions. Confirm RoHS compliance and moisture sensitivity level details via the official datasheet. Check for any product change notices or obsolescence announcements prior to finalizing procurement plans.

Selection Notes

Select this regulator when low noise and high PSRR are critical for RF signal integrity. The 95 µA quiescent current supports battery longevity in portable applications. Ensure the input voltage exceeds the 3.1 V output plus the dropout voltage. Verify that the 150 mA load requirement does not exceed the device's thermal limits in the chosen SOT-23 package.

Part Context

This component belongs to the MicroPower LDO family from Advanced Analog Technology, Inc., which was acquired by Skyworks Solutions. The series is characterized by low noise and high accuracy, targeting portable consumer electronics. The IGV suffix indicates the SOT-23-5 package variant, while the 3.1 denotes the fixed output voltage setting.
