Description
The LDO features a low dropout voltage of 178 mV at 250 mA, which allows it to maintain a regulated output even when the input voltage is close to the output voltage. This regulator operates over a wide input voltage range from 2.3V to 6.0V, adding flexibility for various applications. It also offers high accuracy with a typical output voltage tolerance of ±0.4% at 25°C.
The MCP1700T-3002E/MB is equipped with internal protection mechanisms, such as overcurrent limit and overtemperature shutdown, enhancing reliability. Packaged in a compact SOT-23-3 form factor, it is well-suited for space-constrained designs like portable electronics, IoT devices, and other low-power applications.
