詳細說明
GENERAL DESCRIPTIONThe ADP3331 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3331 operates with an input voltage range of 2.6 V to 12 V and delivers a load current up to 200 mA. The ADP3331 stands out from the conventional LDOs with a novel architecture and an enhanced process that enables it to offer performance advantages and higher output current than its competition. Its patented design requires only a 0.47 mF output capacitor for stability. This device is insensitive to capacitor equivalent series resistance (ESR), and is stable with any good quality capacitor, including ceramic (MLCC) types for space restricted applications.FEATURES High Accuracy over Line and Load: ±0.7% @ 25°C, 1.4% over Temperature Ultralow Dropout Voltage: 140 mV (Typ) @ 200 mA Can Be Used as a High Current (>1 A) LDO Controller Requires Only CO = 0.47 μF for Stability anyCAP = Stable with Any Type of Capacitor (Including MLCC) Current and Thermal Limiting Low Noise Low Shutdown Current: 10 nA Typical 2.6 V to 12 V Supply Range 1.5 V to 11.75 V Output Range –40C to +85C Ambient Temperature Range Ultrasmall Thermally Enhanced Chip-on-Lead™ SOT-23-6 Lead PackageAPPLICATIONS Cellular Telephones Notebook, Palmtop Computers Battery-Powered Systems PCMCIA Regulators Bar Code Scanners Camcorders, Cameras

常見問題解答
What is ADP3331ARTZ?
The ADP3331ARTZ is a low dropout (LDO) voltage regulator designed by Analog Devices. It is capable of providing a stable output voltage with low noise and high accuracy, making it ideal for powering sensitive analog circuits, RF systems, and low power microcontrollers.
How Does ADP3331ARTZ Work?
The ADP3331ARTZ regulates the input voltage to a precise and stable output voltage by using a voltage reference and feedback control. It maintains a constant output voltage even when the input voltage fluctuates, ensuring a reliable power supply for critical components. The LDO design allows it to operate with very low dropout voltage, minimizing power dissipation.
How Many Pins does ADP3331ARTZ have and What are the Functions of the Pinout Configuration?
The ADP3331ARTZ is housed in a 5-lead SC70 package. The pinout configuration includes:
- VOUT: Output voltage pin.
- VIN: Input voltage pin.
- GND: Ground pin.
- BYP: Bypass pin for connecting an external capacitor for improved noise performance.
- ADJ: Adjustable output pin for external voltage setting.
What are the Pros and Cons of ADP3331ARTZ?
Pros:
- Low Dropout Voltage: Performs with low dropout voltage, maximizing efficiency.
- Low Noise: Provides low output noise for noise-sensitive applications.
- High Accuracy: Delivers precise and stable output voltage for critical components.
- Compact Package: The SC70 package is space-efficient, suitable for compact designs.
Cons:
- Current Limitation: May have limitations on maximum output current compared to higher power regulators.
- Thermal Considerations: Requires attention to thermal management for high power dissipation applications.
- External Capacitor: Requires an external capacitor for improved noise performance.
Are There Any Equivalents/Alternatives to ADP3331ARTZ for Recommendation?
- The LM1117 from Texas Instruments is a comparable LDO voltage regulator with similar features.
- An alternative to the ADP3331ARTZ is the MCP1702 from Microchip Technology, offering similar low dropout performance.
