Technical datasheet for the Analog Devices ADP3303A, a high accuracy adjustable 200 mA low dropout linear regulator with anyCAP stability.
The ADP3303A is a precision low dropout (LDO) voltage regulator designed to provide high accuracy over line and load variations. It features an ultralow dropout voltage of 150 mV typical at 200 mA, making it suitable for battery-powered systems where efficiency is critical.
The device utilizes Analog Devices' proprietary anyCAP architecture, requiring only a 1 mF output capacitor for stability regardless of the capacitor type (including MLCCs). It operates with an input voltage range of 3.2 V to 12 V and offers an adjustable output voltage from 2.2 V to 10 V.
| Output Voltage Range | +0.5 V to +12 V |
|---|---|
| Accuracy @ 25°C | -0.8% to +0.8% |
| Dropout Voltage (Typical) | 150 mV |
| Input Voltage Range | 3.2 V to 12 V |
| Output Voltage Adjustment Range | 2.2 V to 10 V |
| Operating Temperature Range | -20°C to +85°C |
The device requires only a 1 mF output capacitor for stability.
Yes, it is stable with all types of capacitors including MLCCs due to its anyCAP architecture.
The device is available in a thermally enhanced TSSOP-14 package.
