Product details
Overview
AAT3220IGY-1.8-T1 from Skyworks Solutions is a 150mA, 1.8V fixed-output NanoPower LDO linear regulator in SC59 package, featuring 1.1µA quiescent current, 200mV typical dropout at 100mA, ±2.0% output voltage accuracy, and integrated short-circuit and over-temperature protection - deployed in battery-powered portable electronics requiring ultra-low standby power.
For engineers reviewing the AAT3220IGY-1.8-T1 datasheet, AAT3220IGY-1.8-T1 pinout, AAT3220IGY-1.8-T1 application, or AAT3220IGY-1.8-T1 equivalent, key selection criteria include guaranteed 150mA output under 1.1µA IQ, thermal shutdown at 140°C, SC59 footprint compatibility, and stable operation with 1µF ceramic output capacitor.
Technical Context
The AAT3220IGY-1.8-T1 employs a PMOS pass transistor architecture enabling ultra-low quiescent current and low dropout without requiring external bias rails. Its internal reference and error amplifier deliver tight DC regulation (±2.0%) and low temperature coefficient (80ppm/°C).
Protection is implemented via dual independent circuits: current-limiting activates at ~150–300mA to prevent damage during overload, while thermal shutdown engages at 140°C with 20°C hysteresis, ensuring safe recovery at ≤120°C - both functions operate without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±2.0% - ensures stable core logic supply for 1.8V I/O microcontrollers and memory interfaces. |
| Max Output Current | 150mA guaranteed - supports moderate-power peripherals like sensors, RF front-ends, or display drivers. |
| Quiescent Current | 1.1µA typical - extends battery life in always-on or sleep-mode applications such as remote controls and wearables. |
| Dropout Voltage | 200mV typ @ 100mA - enables regulation from 2.0V input (e.g., single Li-ion cell at end-of-discharge) while maintaining 1.8V output. |
| PSRR | 50dB @ 100Hz - suppresses low-frequency ripple from switching regulators or noisy battery sources feeding sensitive analog circuitry. |
| ESD Rating | 4kV HBM - provides robust handling margin during PCB assembly and end-user device integration. |
| Operating Temp | −40°C to +85°C - qualified for industrial and consumer portable environments without derating. |
Pinout & Package
Package: SC59 - 3-pin, Pb-free, surface-mount package with 1.575mm × 2.80mm body, 0.95mm lead pitch, and 0.45mm lead width; optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Primary return path for load current and internal bias; must connect directly to low-impedance ground plane to maintain PSRR and transient response. |
| 2 - OUT | Regulated output | Delivers stable 1.8V to load; requires ≥1µF ceramic capacitor placed adjacent to pin for stability and transient suppression. |
| 3 - IN | Input supply | Accepts 2.0V–5.5V input; decoupling capacitor recommended if >2cm from source to minimize line transients and improve ripple rejection. |
Key Features
| Feature | Design Value |
|---|---|
| NanoPower quiescent current | 1.1µA enables >1-year battery life in 10µA-average-current IoT sensors using CR2032 cells. |
| Low-ESR ceramic capacitor support | Stable with ≥1µF X7R/X5R ceramics - eliminates need for costly tantalum or large aluminum electrolytics. |
| Integrated protection | Current limit + thermal shutdown (140°C trip / 120°C recovery) allows indefinite short-circuit survival without external circuitry. |
| High DC accuracy | ±2.0% output tolerance ensures reliable operation of 1.8V logic families (e.g., ARM Cortex-M0+, SPI flash, SDIO) across temperature. |
| Low noise performance | 350µV RMS output noise (10Hz–10kHz) minimizes interference in precision ADC references or audio codec supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1802E/TT | 1.8V, 250mA, 1.6µA IQ, SOT-23-3 - higher output current but 45% higher quiescent current. | Better for higher-load peripherals; less optimal for multi-year battery life in low-duty-cycle devices. | Select when load peaks exceed 150mA but ultra-low IQ is secondary to current headroom. |
| Torex XC6206P182MR-G | 1.8V, 150mA, 1.0µA IQ, SOT-23-3 - identical IQ and current rating, but only 45dB PSRR and no thermal hysteresis spec. | Suitable for cost-sensitive consumer remotes; lacks documented thermal recovery behavior for sustained overload. | Choose for price-sensitive volume production where thermal fault recovery is not mission-critical. |
Compared with MCP1700T-1802E/TT and XC6206P182MR-G, the AAT3220IGY-1.8-T1 uniquely combines 1.1µA IQ, 140°C/120°C thermal hysteresis, and 50dB PSRR in a proven SC59 package - making it optimal for long-life, thermally constrained portable systems demanding predictable fault recovery.

FAQ
What is the minimum input voltage required for AAT3220IGY-1.8-T1 to regulate 1.8V output?
The AAT3220IGY-1.8-T1 requires VIN ≥ VOUT + VDO. With a typical dropout of 200mV at 100mA, the minimum input is 2.0V. At light loads (<1mA), dropout drops further - enabling operation from 1.95V input while maintaining regulation. Absolute minimum VIN is 2.5V per datasheet recommendation to ensure stability across all conditions.
Does AAT3220IGY-1.8-T1 require an input capacitor?
The AAT3220IGY-1.8-T1 does not require an input capacitor for basic regulation, but a ≥1µF ceramic capacitor is strongly recommended when the device is located >2cm from the power source. This improves line transient response and maximizes PSRR - especially critical when powered from switchers or long battery traces.
Can AAT3220IGY-1.8-T1 be used with tantalum output capacitors?
Yes, AAT3220IGY-1.8-T1 is stable with a wide range of ESR values and supports tantalum capacitors. However, ceramic capacitors are preferred due to lower ESR, smaller size, and better transient response. If using tantalum, increase capacitance by 2–3× to compensate for higher ESR and ensure stability under load steps.
What happens during thermal shutdown on AAT3220IGY-1.8-T1?
When die temperature reaches 140°C, AAT3220IGY-1.8-T1 disables its pass transistor and forces output to fall. It remains latched off until die temperature cools to ≤120°C (20°C hysteresis), then automatically resumes regulation. This cycle prevents permanent damage during sustained overload or high ambient conditions.
Is AAT3220IGY-1.8-T1 RoHS and halogen-free compliant?
Yes, AAT3220IGY-1.8-T1 is Skyworks Green™ certified - fully compliant with RoHS Directive 2011/65/EU and halogen-free per IEC 61249-2-21, with bromine <900ppm and chlorine <900ppm. The SC59 package uses matte tin lead finish and Pb-free solderable terminations.
