AMS3102 is a 300mA low dropout voltage regulator from Advanced Monolithic Systems, Inc. It features very low quiescent current and extremely low input-output differential, making it ideal for use in battery-powered systems.
The AMS3102 series consists of positive fixed and adjustable voltage regulators designed for battery-powered systems. Key features include very low quiescent current (0.3mA or less), reverse battery protection, short circuit protection, and internal thermal overload protection.
The device is available in various packages including TO-92, SOT-89, SOT-23, and SOIC. It offers fixed output voltages ranging from 2.0V to 5.0V or an adjustable version with a reference voltage of approximately 1.235V.
| Output Current | 300mA |
|---|---|
| Quiescent Current (10mA load) | 0.3mA or less |
| Dropout Voltage (100mA) | 0.25V |
| Reference Voltage (Adjustable) | 1.235V Typ. |
Fixed versions are available for 2.0V, 2.5V, 3.0V, 3.3V, 3.5V, 4.0V, and 5.0V.
Yes, it includes internal circuitry protected from input fault conditions caused by reverse battery installation.
An output capacitor of 2.2uF or greater is required to ensure device stability.
