Product Overview: MIC5259-1.5YML-TR

The MIC5259-1.5YML-TR is a high-performance, low-dropout regulator (LDO) from Microchip Technology, designed to deliver a fixed output voltage of 1.5V with an input range from 2.3V to 6.0V. It is capable of sourcing up to 150mA of output current, making it an ideal choice for portable devices where efficient power management is critical.

This LDO features an ultra-low quiescent current, typically 18µA, which helps to extend battery life in battery-powered applications. The low dropout voltage, typically 165mV at full load, allows for better regulation of the output voltage as the input voltage approaches the output voltage, thus providing stable operation even during low battery conditions.

Key Features

• Fixed Output Voltage: 1.5V
• High Output Current: Up to 150mA
• Low Dropout Voltage: 165mV at 150mA
• Ultra-Low Quiescent Current: 18µA
• Wide Input Voltage Range: 2.3V to 6.0V
• Stable with Ceramic Output Capacitors
• Thermal Shutdown and Current Limit Protection
• Available in a small 4-pin MLF® package

The MIC5259-1.5YML-TR is also designed with an enable pin, allowing the device to be put into a zero off-mode current state, further reducing power consumption when the regulator is not in use. It is stable with ceramic output capacitors, which are small in size, providing space-saving benefits on the PCB.

With built-in protection features such as thermal shutdown and current limit protection, the MIC5259-1.5YML-TR ensures reliable operation under varying conditions. These safety features protect both the LDO and the powered device from damage due to overheating or overcurrent conditions.

The MIC5259-1.5YML-TR is available in a small, lead-free 4-pin MLF® package, which is ideal for space-constrained applications. Its small footprint and low profile make it suitable for mobile phones, PDAs, digital cameras, and other portable devices where efficient space utilization is crucial.

Whether you are designing a new portable device or optimizing the power management of an existing product, the MIC5259-1.5YML-TR offers a combination of low power consumption, high output accuracy, and robust protection features, making it a versatile choice for a wide range of applications.
