AX1209
2A LDO Linear Regulator with Enable
GENERAL DESCRIPTION
The AX1209 is a low-dropout voltage regulator suitable for various electronic
equipments. It provides constant voltage power source. The dropout voltage of AX1209 is
1.1V in full rated current (2A). This regulator has various functions such as a peak current
protection, a thermal shut down, a short circuit protect.
The AX1209 is available in TO252-5L power package which features small size to
reduce the junction-to-case resistance.
FEATURES
- Operating voltage range: 7V~24V.
- Adjustable Output Version
- Low Dropout voltage: 1.1V (typical) at 2A Output Current.
- Current-Limit and Thermal Shutdown Protection.
- Short circuit protection.
- Shutdown function.
- Built internal driver.
- TO252-5L Pb-Free Package.
