General Description

The EC5232 series of fixed output low dropout linear regulators are designed to meet the new requirements of high PSRR, fast dynamic response, low noise, low dropout voltage and low power consumption in today’s portable battery powered applications such as cellular phones, surveillance system, Bluetooth, wireless and other portable electronic devices.
The short-circuit protection has a fold-back current limiter which will reduce the excessive heat during short circuiting.
EC5232 also have standard Over-Temperature Protection The EC5232 are available in standard SOT23-5L, SOT89 and DFN1x1 4L packages. Standard products are Halogen-free.
