Microchip Technology, Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators MIC5524-2.8YMT-T5

The MIC5524-2.8YMT-T5 is a low-dropout linear voltage regulator capable of delivering a fixed output voltage of 2.8V with a maximum output current of 500mA. It operates within an input voltage range of 2.5V to 5.5V and features a low quiescent current of 38¬µA, making it suitable for battery-powered applications. The device has a high output accuracy of ¬±1% and a power supply rejection ratio (PSRR) of 80dB, ensuring stable performance under varying load conditions. This regulator is designed with a low dropout voltage of 260mV at 500mA, allowing it to maintain regulation even with minimal input-output voltage differential. It includes an auto-discharge feature that activates when the enable pin is low, along with an internal pulldown resistor that disables the output when the enable pin is left floating. The MIC5524-2.8YMT-T5 is housed in a compact 4-pin 1mm x 1mm Thin DFN package, which is advantageous for space-constrained designs. The operating temperature range for this device is from -40¬8C to +125¬8C, making it suitable for a variety of applications, including portable communication equipment, medical devices, and other electronic devices requiring reliable voltage regulation.
