The **ADP3330ART-2.75-R7** is a high-precision, low dropout (LDO) linear regulator manufactured by Analog Devices. It is part of the `anyCAP®` family, known for its stability with a wide range of output capacitors. --- ## 1. Key Specifications The technical parameters of this specific variant are summarized below: | Parameter | Specification | | :--- | :--- | | **Output Voltage (Fixed)** | 2.75V | | **Input Voltage Range** | 2.9V to 12V | | **Output Current** | 200 mA | | **Dropout Voltage** | 175 mV (typical at 200 mA) | | **Package Type** | SOT-23-6 (ART designation) | | **Accuracy** | ±0.8% at Room Temp / ±1.4% Over Line & Load | | **Quiescent Current** | 34 µA (Typical in Light Load) | --- ## 2. Core Features & Components ### anyCAP® Technology The most distinctive feature of this part is its stability. Unlike standard LDOs that require a specific **Equivalent Series Resistance (ESR)** to remain stable, the ADP3330 is stable with: * Multilayer Ceramic Capacitors (MLCC). * Tantalum or Aluminum Electrolytic capacitors. * Even minimal capacitance (as low as 0.47 µF). ### Integrated Protection The internal circuitry includes several safety mechanisms to prevent damage to the chip or the load: 1. **Current Limiting:** Protects the device during short-circuit conditions. 2. **Thermal Overload Protection:** Shuts down the regulator if the junction temperature exceeds safe limits. 3. **Shutdown Mode:** A logic-level input allows the device to be turned off, reducing current consumption to less than 1 µA. --- ## 3. Pin Configuration (SOT-23-6) | Pin No. | Name | Function | | :--- | :--- | :--- | | 1 | **OUT** | Regulated Output Voltage (2.75V). | | 2 | **GND** | Ground Reference. | | 3 | **NR** | Noise Reduction. Connecting a 10nF cap here reduces output noise. | | 4 | **SD** | Shutdown (Active Low). Pull high for normal operation. | | 5 | **ERROR** | Open-collector output that goes low if the output falls out of regulation. | | 6 | **IN** | Input Voltage Supply. | --- ## 4. Part Number Breakdown Understanding the suffix nomenclature: * **ADP3330**: Base part number. * **ART**: Package code for SOT-23 (6-lead). * **2.75**: Fixed output voltage of 2.75 Volts. * **R7**: Refers to the Tape and Reel size (7-inch reel, typically 3,000 pieces). --- ## 5.
