The MIC5319-1.3HYD5 is a high-performance, dual, low dropout regulator (LDO) from Micrel (now Microchip Technology). It's designed to provide a clean and stable voltage source for sensitive electronic circuits, especially in portable and battery-powered applications. One LDO is fixed at 1.3V, while the other is adjustable.

Applications

• Mobile phones: Powering core logic and peripherals in smartphones.
• Tablets: Regulating voltage for processors, memory, and display drivers in tablets.
• Portable media players: Providing a stable voltage source for audio and video processing circuits.
• Digital cameras: Powering image sensors, processors, and memory in digital cameras.
• Wireless modules: Supplying power to RF transceivers and baseband processors in wireless modules.

Features

• Dual LDOs: Provides two independent LDO regulators in a single package, saving board space.
• Low Dropout Voltage: Maintains regulation with very small input-to-output voltage differential, maximizing battery life.
• High Output Accuracy: Delivers precise output voltage regulation, ensuring stable operation of sensitive circuits.
• Low Quiescent Current: Minimizes power consumption when the LDO is not actively supplying current.
• Current Limit Protection: Protects the LDO and the load from overcurrent conditions.
• Thermal Shutdown Protection: Protects the LDO from overheating.
• Small Package: Available in a small DFN package for space-constrained applications.

Benefits

• Space Saving: Dual LDOs in a single package reduces board space requirements.
• Long Battery Life: Low dropout voltage and low quiescent current maximize battery life.
• Stable Operation: High output accuracy ensures stable operation of sensitive circuits.
• Protection: Current limit and thermal shutdown protection prevent damage to the LDO and the load.
• Easy Integration: Simple to integrate into existing systems with minimal external components.

Technical Specifications: The MIC5319-1.3HYD5 operates from a wide range of input voltages, typically from 2.5V to 5.5V. One output is fixed at 1.3V. The other output is adjustable. The maximum output current is 300mA per LDO. The dropout voltage is typically 150mV at 300mA. The quiescent current is typically 20µA. The operating temperature range is -40°C to +125°C. It is available in a DFN package.
