ADP151AUJZ-3.3-R7 詳細描述
Product Overview
The ADP151AUJZ-3.3-R7 from Analog Devices Inc. is a fixed-output linear voltage regulator IC intended for positive-rail regulation in compact surface-mount designs. It provides a single 3.3V output at up to 200mA from an input voltage up to 5.5V, with a maximum dropout of 0.23V at 200mA. The device is packaged in TSOT-23-5 and includes an enable control feature, making it suitable for board-level power sequencing or selective activation of a regulated rail.
Key Features
- Fixed positive 3.3V output with 200mA maximum output current.
- Maximum input voltage of 5.5V, with 0.23V dropout at 200mA.
- Low quiescent current of 20 µA and maximum supply current of 350 µA.
- Power supply ripple rejection of 70dB to 55dB from 10kHz to 100kHz.
- Enable control feature for regulated output activation or deactivation.
- Protection features include over current, over temperature, and under voltage lockout.
- Operating temperature range of -40°C to 125°C in TSOT-23-5 surface-mount package.
Applications
- Regulated 3.3V rail generation for battery-powered portable electronics.
- Point-of-load power for microcontrollers, sensors, or communication modules requiring a fixed positive supply.
- Enable-controlled power domains in embedded systems.
- Compact surface-mount power management on constrained PCB layouts.
Design & Procurement Notes
Design considerations should account for the fixed 3.3V output and 5.5V maximum input, leaving limited headroom for dropout at full load. The 0.23V maximum dropout at 200mA affects input-output voltage margin and full-load regulation headroom. The 20 µA quiescent current supports low-power states, while the enable feature can be used for controlled power-up, deactivation, or rail sequencing. The TSOT-23-5 package supports surface-mount assembly, and the -40°C to 125°C operating range should be considered for environmental placement.
