Jump to Page Section:
Overview
Description
RAA214403 is a low-dropout regulator (LDO) featuring a low-quiescent current and a fixed output voltage of 3.3V. It can efficiently deliver up to 150mA to a load and has a wide input voltage range of up to 40V. This part is available in SOT23 and SOT89 packages.
Features
- Typical low-quiescent current: 3.5µA at no load
- Typical shutdown current (SOT23 package): <0.5µA
- Wide input voltage range: up to 40V with 45V line transient tolerance
- Max output current: 150mA
- Output voltage accuracy: ±3% over line, load, and temperature
- Typical dropout voltage: 0.5V at 100mA
- Fixed output voltage options: 3.3V
- Stable with 2.2µF minimum ceramic output capacitor
- Overcurrent and over-temperature protection
- Junction temperature range: -40 °C to 125 °C
