250ma Ldo Linear Regulators With Current-limiting Switch

The MAX4834 MAX4835 family of low-dropout (LDO) linear Regulators feature an accurate current-limiting Switch with an integrated FLAG or RESET function. These devices operate from 2.5V to 5.5V and deliver up to 250mA of load current at a preset output voltage. Preset output voltage levels are 1.8V/2.5V/2.8V/3.0V/3.3V. The MAX4834 MAX4835 offer a programmable soft- start control function to eliminate false reset during startup. The MAX4834 provides a FLAG function to noti- fy the system when the load current exceeds the limit. The MAX4835 provides a RESET function to notify the system when the output drops below the threshold. Additionally, reverse-current protection prevents cur- rent flowing from the output to the input. Other features include a low 90A quiescent current, a 0.1A shut- down current. The MAX4834 MAX4835 are available in space-saving 6-pin SOT23 and TDFN packages. Each device is speci- fied over the -40C to +85C extended temperature range. Contact factory for other programmed output volt- age versions from 1.5V to 3.3V in 100mV increments. For pin-compatible 100mA versions of this device, refer to the MAX4832 MAX4833. For pin-compatible 500mA versions of this device, refer to the MAX4836/MAX4837. By Maxim Integrated Products
