### ADP3330ARTZ-2.5-R7: Technical Overview The **ADP3330ARTZ-2.5-R7** is a precision, low dropout (LDO) linear regulator part of the anyCAP® family from Analog Devices. It is designed to provide a stable 2.5V output with high accuracy and low noise, making it suitable for sensitive electronic circuits. --- ### Core Specifications The following table summarizes the key electrical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Output Voltage (Fixed)** | 2.5 V | | **Input Voltage Range** | 2.9 V to 12 V | | **Maximum Output Current** | 200 mA | | **Dropout Voltage (Typical)** | 140 mV @ 200 mA | | **Accuracy Over Line/Load** | ±0.8% @ 25°C (±1.4% Over Temp) | | **Package Type** | SOT-23-6 | | **Operating Temperature** | -40°C to +85°C | --- ### Key Electronic Features 1. **anyCAP® Technology**: Unlike standard LDOs that require a specific ESR (Equivalent Series Resistance) for stability, this part is stable with any type of capacitor, including **MLCC (Ceramic)**, Tantalum, or Aluminum. 2. **Ultra-Low Dropout**: With a dropout of only 140mV at full load, it allows the circuit to maintain regulation even when the input voltage is very close to the output voltage, improving efficiency. 3. **Shutdown Mode**: Includes a `SD` (Shutdown) pin. When pulled low, it reduces the ground current to less than 1 µA, making it ideal for battery-powered applications. 4. **Error Flag**: The `ERR` pin acts as an open-collector output that goes low if the output voltage falls out of regulation (e.g., during thermal overload or input undervoltage). --- ### Pin Configuration (SOT-23-6) | Pin No. | Name | Function | | :--- | :--- | :--- | | 1 | **OUT** | Regulated 2.5V Output. | | 2 | **OUT** | Regulated 2.5V Output (Connected to Pin 1). | | 3 | **GND** | Ground Reference. | | 4 | **ERR** | Error Flag (Active Low). | | 5 | **SD** | Shutdown Control (Active Low). | | 6 | **IN** | Input Voltage Supply. | --- ### Implementation Example To use the ADP3330 in a circuit, minimal external components are required: ```c // Circuit Connectivity Logic Input (2.9V - 12V) -> Pin 6 (IN) Capacitor (0.47uF+) -> Pin 6 to GND Output (2.5V) -> Pin 1/2 (OUT) Capacitor (0.47uF+) -> Pin 1 to GND Shutdown -> High for Active, Low for Off ```
