Product details
Overview
AAT3220IGY-3.3-T1 from Skyworks Solutions is a 150mA, 3.3V fixed-output NanoPower LDO linear regulator in SC59 package, featuring 1.1µA quiescent current, 220mV 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-3.3-T1 datasheet, AAT3220IGY-3.3-T1 pinout, AAT3220IGY-3.3-T1 application, or AAT3220IGY-3.3-T1 equivalent, key selection criteria include guaranteed 150mA output under 1.1µA IQ, thermal shutdown at 140°C, SC59 footprint compatibility, and stability with 1µF ceramic output capacitor.
Technical Context
The AAT3220IGY-3.3-T1 implements a PMOS pass transistor architecture enabling ultra-low quiescent current and low dropout performance without requiring external bias rails. Its internal reference and error amplifier deliver tight DC regulation (±2.0%) across -40°C to +85°C ambient.
Protection logic integrates current-limit sensing with die-temperature monitoring: short-circuit events trigger foldback current limiting, while sustained overload raises junction temperature to 140°C, activating thermal shutdown with 20°C hysteresis - ensuring safe operation without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2.0% - enables direct replacement of 3.3V logic rails without external feedback components. |
| Max Output Current | 150mA - supports microcontroller cores, sensors, and RF front-ends in compact portable systems. |
| Quiescent Current | 1.1µA typical - extends battery life in always-on or sleep-mode applications such as remote controls and wearables. |
| Dropout Voltage | 220mV typical at 100mA - allows operation from single-cell Li-ion (3.0V min) or two-cell alkaline (3.2V min) sources. |
| PSRR | 50dB at 100Hz - suppresses switching noise from adjacent DC/DC converters feeding the input rail. |
| Thermal Shutdown | 140°C threshold with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
| ESD Rating | 4kV HBM - meets IEC 61000-4-2 Level 2 for robustness in handheld assembly and end-use environments. |
Pinout & Package
Package: SC59 - 3-pin, Pb-free, surface-mount plastic package (2.85mm × 1.575mm × 0.95mm), 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 3.3V to load; requires ≥1µF ceramic capacitor placed adjacent to pin for stability and transient suppression. |
| 3 (IN) | Input supply | Accepts 3.5V–5.5V input; decoupling capacitor ≥1µF recommended near pin to minimize input impedance and improve line rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 1.1µA quiescent current enables >10-year battery life in coin-cell–powered IoT sensors with 10µA average system load. |
| Single-capacitor stability | Stable with 1µF ceramic output capacitor - eliminates need for costly tantalum or large electrolytic capacitors, reducing BOM cost and board area. |
| Integrated dual protection | Current-limit + thermal shutdown co-located on-die - avoids discrete protection ICs and simplifies layout for high-reliability portable designs. |
| Low-temperature drift | 80ppm/°C output voltage coefficient - maintains <±1% total variation across full -40°C to +85°C industrial range without calibration. |
| High PSRR at low frequency | 50dB rejection at 100Hz - effectively filters ripple from noisy switchers or aging batteries, preserving ADC reference integrity and RF synthesizer phase noise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3302E/TT | 1.6µA IQ, 600mV dropout at 250mA, SOT-23-3 package | Higher dropout limits use with single Li-ion below 3.9V; larger package increases board area | Select when higher output current margin is required and 0.5µA extra IQ is acceptable. |
| Torex XC6206P332MR-G | 1.0µA IQ, 250mV dropout at 100mA, SOT-23-3 package | Slightly higher dropout and 100mA max rating reduce headroom for peak loads | Prefer for cost-sensitive designs where 150mA burst capability is not needed and footprint matches. |
Compared with MCP1700T-3302E/TT and XC6206P332MR-G, the AAT3220IGY-3.3-T1 delivers optimal balance of ultra-low IQ, 150mA delivery, and SC59 compactness - making it uniquely suited for space- and battery-life–constrained portable subsystems where every µA and mm² matters.

FAQ
What is the maximum input voltage for AAT3220IGY-3.3-T1 at 85°C ambient?
The maximum continuous input voltage for AAT3220IGY-3.3-T1 at 85°C ambient is 4.33V, calculated using PD(MAX) = 200mW, VOUT = 3.3V, IOUT = 150mA, and IGND = 1.1µA. This ensures thermal safety within the 200°C/W ΘJA limit. The absolute maximum VIN rating remains 6V per datasheet, but operation above 4.33V at 85°C requires duty-cycled loading to avoid thermal shutdown.
Does AAT3220IGY-3.3-T1 require an input capacitor for stable operation?
AAT3220IGY-3.3-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 input transient response and maximizes PSRR - especially critical when powered from switchers or high-impedance battery sources. CIN placement must be adjacent to the IN pin.
Can AAT3220IGY-3.3-T1 operate with a 0.47µF output capacitor?
Yes, AAT3220IGY-3.3-T1 is stable with output capacitors as low as 0.47µF, though 1µF is recommended for optimal load transient response and worst-case temperature stability. The device's internal compensation is designed for wide ESR tolerance, supporting ceramic, tantalum, and aluminum electrolytic types - but ceramic is preferred for lowest noise and smallest footprint.
What happens during a sustained short-circuit event on AAT3220IGY-3.3-T1?
During a sustained short-circuit, AAT3220IGY-3.3-T1 activates current-limit protection first, clamping output current to ~350mA. If power dissipation causes die temperature to reach 140°C, thermal shutdown engages, turning off the pass device. Output remains disabled until junction temperature falls below 120°C - preventing permanent damage and enabling automatic recovery once fault clears.
Is AAT3220IGY-3.3-T1 compatible with lead-free reflow processes?
Yes, AAT3220IGY-3.3-T1 is Pb-free and qualified for standard lead-free reflow profiles, including peak temperatures up to 260°C for 10 seconds. Its SC59 package meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), eliminating bake requirements prior to assembly. Skyworks Green™ compliance confirms halogen-free construction.
